This is a digital copy of a book that was preserved for generations on library shelves before it was carefully scanned by Google as part of a project 

to make the world's books discoverable online. 

It has survived long enough for the copyright to expire and the book to enter the public domain. A public domain book is one that was never subject 

to copyright or whose legal copyright term has expired. Whether a book is in the public domain may vary country to country. Public domain books 

are our gateways to the past, representing a wealth of history, culture and knowledge that's often difficult to discover. 

Marks, notations and other maiginalia present in the original volume will appear in this file - a reminder of this book's long journey from the 

publisher to a library and finally to you.

Jn EstimaU of the PhUosophicai Character of Dr PrietiUy. 
By William Hkney, M. D., F. R. S. 8ic &c.» 

J. HE principal source of the materials of tiie following sketch, 
ia the work in which the discoveries of Dr Priestley were oii^ 
Dally announced to the public It con^sts of six volumes in 
octavo, which were published by him at intervals between the 
years 1774 and 1786 ; the first three under the title of " Expe- 
riments and Observations on different kinds of Air ;" and the 
last three under that of " Experiments and Ohservadons rela- 
ting to variuis Branches of Natural Philosophy, with a continua- 
tion of the Observations on Air." . These volumes were after- 
wards methodized by himself, and compressed into three octavos, 
which were printed in 1790: As a record of facts, and as a 
book of reference, the systematized work is to be preferred ; 
but as affording materials for the history of that department 
of science which Dr Priestley cultivated with such extraordinary 
success, and, still more, for estimating the value of his discove- 
lies, and adjusting his station as an experimental philosopher, 
the simple narrative, which he. originally gave in the order of 
time, supplies the amplest and the firmest ground-w<H-k. 

In every thing that respects the history of this branch of ex- 
perimental jdiilosophy, the writings and researches of Dr Priest- 
1 ley, to which I have alluded, are peculiarly instructive. They

are diatingiuBhed by great merits, and by great defects ; tbe Ut- 
ter of which are wholly undi^uised by thear author. He ua- 
veilB, with perfect fi'anlcness, the whole process of reasoning, 
which led to his discoveries ; he pretends to no more sagacity 
than belonged to him, jind sometimes disclaims errai that to 
which he was ffurly entitled ; he freely acknowledges his mis- 
takes, and candidly confesses when his success was the result of 
accident, rather than of judicious anticipation ; and by wnting 
Jiistorically and analytically, he exhibits tbe progressive improve- 
ment of his views, from their first dawnings to their final and di». 
duct development. Now, with whatever delight we may con- 
template a systematic arrangement, the materials of which have 
been judiciously selected, and from which every thing has been 
excluded that is not essential to the harmony of the general de- 
ogn, yet there can he do question that, as elucidating the opera- 
tions of the human mind, and enabling us to trace and appred- 
ate its powers dT invention and discovery, the analytic method 
<^ writing has decided advantages. 

To estimate, justly, the extent of Dr Priestley's clmm to philo- 
sophical reputation, it is necessary to take into account the state 
of our knowledge of gaseous chemistry at the time he b^;aD 
his inquiries. Without underrating what had been already done 
by Van Helmont, Ray, Hooke, Mayow, Boyle, Hales, Macbride, 
Black, Cavendish, and scHne others, Priestley may be safely af- 
firmed to have entered upon a field, which, though not altoge- 
ther untitled, had yet been very imperfectiy prepared to yield 
the rich harvest, which he afterwards gathered from it. The 
very implements with which he was to work were for the most 
part to be invented ; and of the merits of those which he did in- 
vent, it is a sufficient proof that they continue in use to tins day, 
with no very important modifications. All his contrivances for 
collecting, transferring, and preserving diiferent kinds of lur, and 
for submiiting those lurs to the action of solid and liquid sub- 
stances, were exceedingly simple, beautiful, and efi^ectual. They 
were chiefly, too, the work of his own hands, or were construct- 
ed under his directions by unskilled persons ; for the dass of in- 
genious artists, from whom the chemical philosopher now derives 
such valuable aid, had not then been called into existence by 
the demands of the sdence. With a very limited knowledge of 



th£ Philosophical Character of Dr Priestley. g 

the general prinaples of chemistry, and almost without praiAice 
in its mort commra manipulations ; — teitricted by a nartoir ith 
axne, oad at fint witfa little pecumsiy aseistance from othen^— 
compelled, too, to devote a large pt^tion of his time to- other 
pressipg occupationB, he neverthelesB surmounted all obstacles ; 
and in tbe care«' of discovery outBtri{^>ed many who had long 
been exclusively devoted to soienoe, and were richly provided 
with all appliances and means for its advancement. 

It is well known that the accident of living noar a- public 
brewery at Leeds, first directed tbe attention of Dr Priestley to 
pneumatic chemistry, by casually presentii^ to his observation 
the appearance attmiding the extinction of Ugfated chips of wood 
in the gas wlucfa floaSs over fennenung Jiquors. He remarlaed, 
that the smojce formed distinct clouds floating on the surface of 
the atmosphere of thevcMel, and that this mixture of air and 
smoke, when throi^n over the ndesof the vat, tell to the ground ; 
from whence he deduced the greater weight of this sc^t of air 
than of atmospheric air. He next found that water imbibes the 
new air, and again abandons it when bo^ed or frozen. These 
more obvious properties of fixtjd air having been ascertained, he 
extended his inquiries to its other qualities and relations ; and 
was afterwards led by analogy to the discovery of various other 
gases, and to the investigation of their characteristic properties. 

It would be inconsistent with the scope of this essay to give 
a full catalogue of Dr Priestley's discoveries, or to enumerate 
more of them than are necessary to a just estimate of his philo- 
sophical habits and charactfr. He was the unquestionable au- 
thor of our first knowledge of oxygen gas, c^ nitrous oxide, of 
muriatic, sulphurous, and flu(»- add gases, of ammoniaoal gas, 
and of its condensation into a solid form by the acid gases. Hy- 
drogen gas was known hefon bis time; but he greatly extended 
our acquaintance with its properties. Nitrous gas, barely dis- 
covered by Dr Hales, was fir^ investigated by Priestley, and ap- 
plied by him to eudiometry. To the chemical history of the 
acids derived from nitre, he contributed a vast acces^n of ori- 
ginal and most valuable facts. He seems to have been quite 
aware that those acids are essentially gaseous substances, and 
that they might be exhibited as such, provided a fluid could

be fouDd that is incapable of absorbiDg or acting upon them*. 
He obtained, and distinctly described-|-, the curious crystalline 
ctunpound of sulphuric acid with the vapour of^ nitrous acid, of, 
more correctly, of sulphuric and hyponitrous acids, which, being 
of rare occurrence, was forgotten, and has since been redisco- 
vered, like many other neglected antidpatioaa of the same au- 
thor. He greatly enhtrged our knowledge of the important class 
of metals, and traced out many of their most interesting relations 
to oxygen and to acids. He unfolded, and illustrated by sim- 
ple imd beautiful experiments, distinct views of combustion ; of 
the respiration of animals, both of the inferior and higher classes ; 
of the change produced in organized bodies by putrefaction^ 
' and of the causes that accelerate or retard that process ; of the 
importance of azote as the characteristic ingredient of animal 
substances, obtainable by the action of dilute nitric acid on mus- 
cle and tendon ; of the functioas and economy of living T^;eta- 
Ues ; and of the relations and subserviency which exist between 
the animal kingdoms. After trying, without eSect, a variety 
of methods, by which he expected to purify air vitiated by the 
breathing of animals, he discovered that its purity was restored 
by the growth of living and healthy vegetables, freely exposed to 
the solar Ught. 

It is impossible to account for these and a variety of other 
discoveries, of less importance singly, but forming altogether a 
tribute to science, greatly exceeding, in richness and extent, that 
<^ any contemporary, without pronouncing that their author 
must have been furnished by nature with intellectual powera 
far surpassing the common average of human endowments. If 
we examine with which of its various faculties the mind of Si 
Priestley was most eminently gifted, it will, I believe, be found 
^lat it was most remarkable for clearness and quickness of ap- 
prehension, and for rapidity and extent of associadon. On th^e 
qualities were founded that apparently intuitive perception of 
analogies, and that happy facility of tradng and pursuing them 
through all their consequences, which led to several of his most 
brilliant discoveries. Of these analc^es many were just and 
kgibmate, and have stood the test of examination by the clearer 
light, unce reflected upon them from the improved condition of

sraettce. But, in other cases, fats oDalogies were fimciful and aa- 
founded, and led him far astray from the path which might 
have conducted him directly to truth. It is curious, however, 
as he himself observes, that in missiDg one thing, of which he 
was in search, he often found another of greater value. In such 
cases, his vigilance seldom failed to put him in full possesutm of 
the treasure upon which he bad stumbled. Finding by expoi- 
ence, how much chance had to do with the success of his inves* 
ligations, he resolved to multiply experiments, with the view of 
increasing the numerical probabilities of discovery. We find 
him confessing, on one occa^on, that he " was led m, by a ran- 
dom e^ipectation of some change or other taking phu:e.^ In 
other instances, he was influenced by theoretical views of so 
flimsy a texture, that they were dispersed by the first appeal to 
experiment. " These mistakes,^ he observes, " it was in my 
power to have concealed ; but I was determined to show bow 
little mystery there is in the bu^ness of experimental philosophy; 
and with how httle s^acity, diticovertes, which some persons are 
pleased to consid^ great and wonderful, have been nude." 
Candid acknowledgments of this kind were, however, turned 
a^nst him by persons envious of hb growing fame ; and it waa 
asserted that o^/ his discoveries, when not the fruits of plagiarism, 
were " lucky guesses," or owing to mere chance*. Such de- 
tractors, however, could not have been aware of the great 
amount of credit that is due to the philosopher, who at once 
perceives the value of a casual observation, or of an unexpected 
result; who discriminates what facts are trivial, and what are 
important ; and selects the latter, to guide him through difScult 
and perplexed mazes of investigation. In the words of D'AIem- 
bert, " Ces hazanh ne tant que pour ceux <piijouent ^en.'" 

Th« talents and qualifications which are here represented as 
having characterized the nund of Dr Priestley, though not of 
the rarest kind, or of the highest dignity, were yet such as ad- 
mirably adapted him for improving chemical saence at the time 
when he lived. What was then wanted, was a wider field, of

qtedfic gravity, of 'absolute and relative weights, and of crystal- 
line structure, on which the more exact science of our own times 
is firmly based, andfrtHn which its evidences must henceforward 
be dedvsd. Nor could such refined investigations have then 
been euried on with any success, on account of the imperfec. 
tkm of pbiiogophical instruments. It would have been fruitless, 
also, at that time, to have indulged in speculations respecting tbe 
ultimate constitution of bodies ; — speculations that have no solid 
ground-work, except in a class of &ctB developed within tbe litat 
thirty-five years, all tending to eslabUsh the laws of combination 
in definite and in multiple propcmianB, and to support the still 
pux« extensive generaliKation, which has been reared 1^ the 
genius of Dsdt(X). 

. It was, indeed, by tbe activity of his intellectual faculties, 
eather than by their reach or vigour, that Dr Priestley was 
enabled lo render such important services to natural stnence. 
We should look, in vain, in aoy thing that be has achieved, for 
demonstratioDs of that powerful and sustained attention, whidi 
enables the mind to institute dose and accurate compariaiBis ;— 
to trace resemblances that are far from obvious ;— <nd to dis- 
criminate ^fferences that are recondite and cbecun. The ana^ 
k^lies which caught his observation lay near the surface, wd 
were eagerly and hastily pursued ; ofiten, indeed, beyond the 
boundaries within which they ought to have been civcumscribf 
cd. Quick as his mind was in the perception of reserablaoces, 
it appears (probably for that reason) to have been little adapt- 
ed for those pn^und and cautious abstractiuis, which supply 
the only solid foundations of general laws. In sober, patient, 
and successful inductiwi, Prjestley must yield the palm to many

Among the defects of his {^liloBophical habits, may be re- 
marked, that he frequently pursued an object ti inquiry too es- 
clusiTeJy, Deglectiag others, vhich were necessarily coonectod 
with it, and which, if investigated, would hare thrown great 
light on the main reneardi. As an instance, vaay be menticHted 
hia waittiog to examine the rtjation of gases to water. This 
tdation, of which he had indistinct glimpses, was a source <^ 
perpetual embanrasunent to him, and led lum to imagine cfaang- 
ts in the intimate constitution of gases, which were in fiut doe 
to nothing more than an interchange of place betweoi the gat 
in the vatex and that above the water, or between the former 
and the external atmosphere. Thus he erroneoudy suppowd 
that hydrogen gas was transmuted into azotic gas, by reaun< 
tng loag confined by the water of a pneumatic dstem. Tha 
lame eager direction of his mind to a ungle object, caused him 
also to om'look sevnal new substances, which he must ne> 
eessarily have obtained, and which, by a more wati^ul care, be 
night have secured and identified. At a very eariy period t^ 
lus inquiries, (viz. before November 1771), he was in possessioB 
of oxygen gas from saltpetre, and had remarked its striking ^ 
feet on the flame of a candle ; but be pursued the subject no 
&uiher unnl August 1774, when he again procured the iwne 
kind of gas from the red oxide of mercury, and, in a less pure 
state, from red lead. Placed thus a second time within his 
grasp, he did not omit to make prize of this, his greatest, dis. 
covery. He must, also, have obtained chlorine by the sotuticm 
c^ manganese in spirit of salt ; but it escaped his notice, because, 
bong received over mercury, the gas was instantly abswbed*. 
If he had employed a bladder, as Sdieele afterwards did, to 
collect the produce of the same materials, be could not have 
fuled to witicipate the Swedish philosc^her, in a discovery not 
less important than that of oxygen gas. Carbonic oxide early

being aware of its true diBtinctions from other kinds <tf -inflam. 
mable air ; and it wasrestrved for Mr Cnrickshank of Wodwich 
to unftdd its real nature and characters. It is rernaricaUe also, 
that in various parts of his works, Dr Priestley has stated fasts 
that might have given him a hint of the law, «nce unfolded by 
the sagacity' of M. Gay-Lussac, " that gaseous eubstances com- 
bine in definite volumes." 
He shows that 

1 measure of fixed air unites with 1$ measure of alkaline air, 

1 measure of mlphurouB acid with S measures of do. 

1 measureof fiuor acid with St measures of do. 
: 1 measure of oxygen gas with S measures nitrous, very 
nearly ; 
and that by the decomposiuoa of 1 vol. of ammonia, 3 vols, of 
hydrogen are evolved. 

Let not, ■ however, fulures such as these tQ reap all that was 
within Ins compass, derogate more than thdr due share from 
the merits of Dr Priestley ; for they may be traced to that very 
ardour of temperament, which, though to a certain degree a 
di^squalification for close and correct observation, was the vital 
and sustaining prin<npte of his zealous devotion to the pursuit 
of sdentific truth. - Let it be remembered, that philosophers of 
the lofdest pretensicHis are chargeable with similar overughts ;^— 
that even Kepler and Newtoa overlooked discoveries, upon the 
very confines of which they trod, but which they left to coni^r 
glory on the iiames of less illustrious followers. 
■ Ctf the general correctness of Dr Priestley's experiments, it is 
but justice to him to speak with decided approbation. In some 
instances, it must be ackoowledged, ihat his results have been 
recti6ed by subsequent inquirers, chiefly as respects quantitjea 
and proportions. But of the immense number of new facts 
originating with him, it is surprinng how very few are at vari- 
ance with recent and correct observations. Even in these few 
examples, his errors may be traced to causes connected with the 
actual condition of snence at the time ; sometimes to the use of 
impure substances, or to the imperfection of his instruments of 
research ; but never to carelessness of inquiry or negligence of 
truth. Nor was he more remarkable for the zeal with which 



the PkUoiophkai CkaraOer ofDr PnetUey. 

he sought satiBfactory evideoce, thwi for the fiddity wkh which 
he T^torted it. In do one instoooe is he chargeable wilh dub- 
ststing, or even with straining or colouring, a fact, to suit an 
hypothecs. And though this praise may, dmibtless, be craw' 
ceded to the great majority of experimental ]:^ik«opher8, yet 
Dr Priestley was ungularly exempt from that dispontioo to 
view phenomena through a coloured medium, which sometimes 
steals imperceptibly over minds of the greatest g^ieral probity. 
This security be owed to his freedom from all undue attach- 
ment to hypotheses, and to the facility with which he was accua- 
tomed to frame and abandon them ;— a fadhty resulting not 
fiom habit only, but Irom principle. " Hypotheses^ be pro- 
nounces, in one place, " to be a cheap commodity i" in another 
to be ** of no value except as the parents of facts C and so far 
, as he was himself concerned, he exhorts his readers " to cchiu- 
der new facts only as discoveries, and to draw oonclunons for 
themselves." The only exception to this general pruse is to be 
fMind in the. pertinacy with which he adhered, to the 1a>t> to 
the Stahtian hypothesis of phlogiston ; and in the anxiety which 
he evinced to reconcile to it new phenranena, which were con- 
iddered by almost all other philosophers as proofs of its utter 
unsoundness. But thb anxiety, it mu^ be remembered, was 
chiefly ^parent at a period of hfe, when most men feel a reluc- 
tance to change the principle of arrangement, by which they 
have been long accustomed to class the multifarious particulars 
.of their knowledge. 

In all those feelings and habits that connect the purest morals 
with the highest philosophy (and that there is such a connec- 
tion no one can doubt), Dr Priestley is entitled to unqualified 
esteem and admiration. Attached to science by the most gene- 
rous motives, be pursued it with an entire disregard to his own 
peculiar interest He neither sought, nor accepted when offer- 
ed, any pecuniary aid in bis philosophical pursuits, that did not 
leave him in possession of the most complete independence of 
thought and of action. Free from all little jealousies of con- 
temporaries or rivals, he earnestly invited other labourers into 
the field which he was cultivating; gave publicity,. in his own 
volumesr to their experiments ; and with true candour, was as 
ready to record the evidence which contradicted, as that which

In pekiect cooastency with that liberality of temper which 
has been ascribed to Dr Priestley, it may be remarked also, that 
be uxdi the most enlao^^ views of the scope and objects of Na- 
iural Science. In various passages of bis *rarks he has eafcaced, 
irith wiarm and impreeeive eloquence, the conaderations that 
4ow from ibo'contemplation of those arrangements in the mu 
-tural woiU^-wtncb are not only perfect in themselves, hut are 
esssnUal parts of one grand and harmonious design. He strenu- 
ously recommends experimental philosophy as an ^reeaUe re- 
Uef from employments that excite the feelings or overstrain the 
aUentionj and he proposes it to the young, the high<bom, and 
,the affluent, as a source of pleasure unalloyed with theanxietiea 
and a^tatioos of public life. He regarded the benefits of its 
investigations, not merely as issuing in the ooqitirement of new 
facts, however strilung and valuable ; nor yet in the deduction 
of general principles, however sound and important ; but as 
bamng a necessary tendency to increase the intellectual power 
and energy of man, and to exalt human nature to the highest 
dignity of whidi it in suscep^ble. The springs of such in- 
quiries be represents as inexhaustible; and the prospects, that 
may be gained by successive advances in knowledge, as in them- 
selves " truly sublime and glorious." 

Into our estimate of the intellectual character of an indivi- 
dual, the extent and the comprehensiveness of his studies most 
always enter as an essential dement. Of Dr Priestley it may 
be justly affirmed, that few men have taken a wider range over 
the vast and diversified field of human kiiowledge. In devo- 
ting, through the greater part of his life, a large portion of bis 
attention to theological pursuits, he fulfilled, what he strongly

uttderatanding and capadty for profound research, yet it woold 
be .difficult to |»oduce an instanoe of a writer more eminent 
for the variety and versatility of his talents, or more meritorious 
for thw aealous, unwearied, and productive employment. 



APFEMDIX. 

Since the foregoing pages were written, I bave added a few 
remarks on a passage contained in a recent work of Victra- 
Cousin, in which that writer has committed a material error as 
to the origin of Ur Priestley's philosophical discoveries. <* I^a 
chimie," he observe^ " est une creation du dixhuiti^me siecle, 
une creation de la France ; c'est I'Europe entiere qui a appel^ 
chimie Pranfaise le mouvement qui a imprime h cette belle sci- 
ence une impulsion si forte et une direction ri sage ; c^est 4 
Texemple et sur les traces de Lavtnsier, de Guy ton, de Four- 
croy, de Berthollet, de Vauquelin, qui se sont formes et que 
marcbent encore les grands chimistes Strangers, ici Priestley et 
Davy ; U Klaproth et Berzelius.'" (Cours de THistoire de la 
Fhiloeopbie, torn i. p. &5.) 

It is to be lamented that so enlightened a writer as Victor 
Couran, yielding, in this instance, to ihe seduction of national 
vanity, should have advanced pretenaons in bdialf of his 
countrymen, which have no foundation in truth or justice. No- 
thing can be more absurd or unprofitable than to claim honours

may be at once set ^de hj ao appeal to public and authentic 
records. 

- It was in England, not in France, that the first decided ad- 
vances vere made in our knowledge of elastic fluids. To say 
nothing of anterior writers, Dr Black had traced the causticity 
acquired by alkaUes, and by certain earths, to thrar being freed 
from combination with fixed air ; and Mr Cavendi^, in 1766, 
had enUrged our knowledge of that gaa and of inflammable 
air. In England, the value of these difcovmes was fully ap. 
preciated ; in France, little ot no attentim was paid to them, 
till the philosophers of that country were roused by the striking 
- phenomena exhibited by the experiments of Priestley. Lavoisier, 
it is true, had been led, by an examination of evidence derived 
from previous writers, to discard the hypothesis of phlogiston. 
The discovery of oxygen gas by Dr Priestley not only completed 
the demonstration of its fallacy, but served as the ctnu^-stoiM 
of a more sound and consistent theory. By a series of researches 
executed at great expense, and with consummate skill, the 
French philosopher verified in some cases, and corrected in 
others, the results of his predecessors, and added new and im- 
portant observations of his own. Upon these united, he 
founded that beautiful system of general laws, chiefly relating 
to the absorption of oxygen by combustible bodies, and to the 
constitution of acids, to which alone the epithet of the Aoti^ 
phlogistic or French theory of chemistry is properly applied. 
Of the genius manifested in the construction of that system, and 
the taste apparent in its expoution, it is scarcely possible to 
speak with too much praise. But it is inverting the order of timt 
to assert, that it had any share in giving orijpn to the researches 
of Priestley, which were not only anterior to the French theory, 
but were carried on under the influence of precisely oppo^te 
views. This, too, may be asserted of the discoveries of Scheele, 
who, at the same period with Dr Priestley, was following, in a 
distant part of Europe, a scarcely less illustrious career. 

It is the natural progress of most generalizations in srience, 
that, at first too hasty and comprehensive, they require to he 
narrowed as new facts arise. This has happened to the theory 
of Lavoisier, in consequence, of its having been discovered, 

,KW|C

that combustion is not necessarily acconopatiiecl widi an absorp- 
tion of oxygen, and that acids exist independently of oxygeo, 
regarded by him as the general acidifying principle. But after 
all the deductions that can justly be made on that account 
from the merits of Lavoisier, he must still hold one of- the 
highest places amaug those illustrious men, who have advanced 
chemistry to its present rank among the phyacal sdences. It 
is deeply to be lamented that his fame, otherwise unsullied, 
should have been stained by his want of, candour and justice 
to Dr Priestley, in appropriating to himself the discovery of 
oxygen gas. This diarge, c^ten jnreferred and never answered, 
would not have been revived in this place, but for the claim 
so recently and indiscreetly advanced by M. Victor Counn. 
To the credit of Dr Priestley it may be observed, that in 
asserting his own ri^t, he exercised more forbearance than 
could reasonably have been expected under such drcumstances- 
Id an unpublished letter to a friend, he thus alludes to the 
subject of M. LavcHuer's pla^^arism. ** He,^ (M. HAvoisier) 
" is an Intendani rf the FmanceSy and has much public 
business, but finds leisure for various philosophical pursuits, 
Jbr which he is exceedingly well qualified. He ought to have 
acknowledged that my giving him an account of the air I had 
got from Mercfirius Calcmatug, and buying a quantity of M. 
Cadetvwhile I was at Paris, led him to try what air it yielded, 
which he did presently after I left. I liave, however, barely 
hinted at this in my second volume.*" The communication 
alluded to was made by Dr Priestley to M. Lavoisier in October 
ITIi i and the memcnr, in which the latter assumes to himself 
the discovery that mercurius calcinatua (red oxide of mercury) 
affords oxygen gas when distilled per scy was not read to the 
Academy of Sciences before April 1775 f. In evindng so little 
irritability about his own claim, and leaving its vindication with 
oalm and just confidence to posterity, the English philosopher 
has lost nothing of the honour of that discovery, which is now 
awarded to him, by men of science ^f every country, as solely 
and nndividedly his own.

Account efihe Russian Vapour-Bath. By T. S. Traili., M. D. 
Communicated by the Author.* 

T^HK existetKC in Hoilriiu^ of two eataUishraeBtB wbere the 
Rosnui Vapour.BBth is usedi brought to my recollection the 
descriplioro ginn byAcerU, and other travelien, of the iotense 
beat aoA sudden tranutioa to cold, so much relished by the na- 
tiiHis of Northern Europe, and r^ed my curiosity to experi- 
snce in my own person the eSfacts of this ungular species of 
batfaiiig. I was fonher indoeed to take this step from finding 
myBtil suddenly opfseBied with a violent feverish cold, whii^ 
raised tny pulse connderaUy above 100°, and rendered me lit- 
tle able to jcnn the public dianer-t^e in the Apollo Saal. 

Accompanied by two friends who widied to make the same 
experiment, I repured to the AxEXAinxsBAD, whidi is under 
the directitm of its propriety, a Jewish fAyncian, who had 
Itbendly open^ it gratuitously to the members of the Societyof 
Na^r/bracher^ then assembled at Hamburgh. We were ushei'- 
ed into a very neat saloon, provided with nx couches, beside 
each of which stood a dresnng table, and a convenient appara- 
tas for suspending the clothes of the baUier. Here we un- 
dressed, and were furnished with long flannel dresstng-gowns and 
warm slippers, after which we were all conducted into a small 
hot apartment, where we were denred to lay aside our gowns 
and slippers, and were immediately introduced into the room 
called the bath, in which the dim light admitted through a 
single window of three panes, just sufficed to shew us that 
there were in it two persons, like ourselves in purU tiaturali- 
bta ; one of whom was an essential personage, the operator, the 
other « gentleman just finishing the process by a co[uous affu- 
sion of cold water over his body. This sudden introduction in> 
to an Atmosphere of hot steam was so oppresave, that I was 
forced to cov^ my face with my hands, to moderate the pain- 
ful impre^tai on the lips and nostrils, and was compelled to 
withdraw my head, as murli as posable, from the most heated

part of the atmos^diere, bj sitting domi on a low bench which 
ran along two udes of the bath. 

At first our modesty felt some alaim at our perfect nudity, 
and that of those around us ; but I bochi JeU that it would be 
absolutely imposable to endure the contact of any aoit of cove*- 
ing of our nakedness in a temperature so high ; and ooostJed mj^ 
self with the reflection, that it was no worse than the promis- 
cuous bathing I had so ofWn practised at the sea-b^ha of 
Liverpool ; an exposure which, not withstand ing my pasnon fiar 
bathing, was always disagreeable at the comnunoement of each 
season ; but to which cuatiMn had soon rendered me indiflerenL 
' The bath-room is about 15 feet kng^ by about b> .loueb in 
breadth. It is liaed with wood, rendered quite black by con- 
stant immermoQ in hot steam. On two sides it has three tien 
of benches, or rude couches, each of which is calculated to 
hold two persons, with their feet toward each o^er ; so that 
twelve persons might bathe as the same time. The lowest 
bench projects farthest into the room ; they rise two feet above 
each other; and each has a wooden pillow at the ends. 

In one comer of the farther end of the apartment stands 
the furnace, which is supplied with fuel from without, and baa 
a thin arch of fire-brick turned over the fixe, against which the 
flame reverberates, until the arch is red hot . Over this arch is 
built a anall brick chamber, the only aperture to which is by 
a small door about two feet long, and flfbmi inches -wide, 
opening nearly to the level of the arch. To increase the heaU 
ed surface, numerous small earthen jars, or broken pottery, 
are piled on the arch, and all are kept up to a low red heali 
On these, a ba«n of water is occasionally dashed ; and the 
clouds of steam which instantly issue . from the door of the 
heated chamber, form the source of beat employed to maintain 
the temperature of the bath. 

In the corner opposite to the furnace is a reservtnr of cold 
water, into which the person who manages the bath frequently, 
during our stay in the bath, plunged to oool his surface; a 
precaution not unnecessary for an individual who 'is exposed 
daily oght hours, stark naked, to a temperature quite oppre»- 
nve to the luuniliated. Yet this exposure and this allfimatbn 
cannot be unhealthy ; for I never saw a more athletic man thaM

this person, who informed me that he had been constantly en> 

gaged in this occupation for sixteen or eighteen months. 

The centre of the ceiling of the bath-room is perforated by 
numeTous holes which allow a copious shower-bath of cold 
wata* to descend on the head of the bather, when a Talve ' 
managed by a cord is opened. 

Such is the apparatps necessary for a Russian vapour-bath. 

After remuning some time in the bath, the first sensaticHts 
of oppressive heat subsided, and I ascended to the second tier 
of benches, the wood of which, however, was somewhat cooled 
by the plentiful affusion of cold water. At each remove this 
f^ration is repeated ; otherwise the contact of the wood would 
be insupportable to the skin. It is needless to say, that the 
pcrsfnration very soon began to run from every pore, not mere- 
ly aa a moist exhalation, but ran oiF in copious streams. This 
greaUy moderated the sensation of heat. 

After lying extended for some lime on the second tier of 
benches, a bucket of cold water was dashed on the upper onej 
and we removed there ; but the heat, so near the ceiling, was 
fully as oppressive as on first entering ; and I found it neces- 
sary to allow the lur to enter my nose through my fingers. If 
I inhaled it with the mouth wide open, I felt an oppressive 
heat in my chest ; but by degrees even this degree of heat be- 
came supportable ; though I never was able to sit upright on 
the upper bench ; so strong was the temperature of the humid 
atmosphere close to the c^ng. 

While we were groping our way from bench to bench, the 
assistant more than once plunged headlong into his cold batli, 
to refresh himself ere he commenced on us the next part of bit 
professional occupation. 

We were one by one requested to descend to the second tier ; 
and the assistant, grasping in his hand a bundle of birch rods, 
began assiduously to whip his patients, who lay extended on the 
bench at full length, from head to heel. This application dif- 
fers essentially from the well remembered scholastic birch di^ 
cipline ; for the leaves are left on the twigs, and tli.e sensations 
produced in no way resemble the efiect of the instrument em- 
ployed in English schools to c<mvey & Jv,ndament(d knowledge 
of Greek and Latin into the heads of our yoiith. In fact, this .

specieB of whipping is performed very dexterously, with a sort 
of brushing motion, from the shoulders downwards ; sod the 
application becomes gena^ oyer the body and limbs, as the 
bather turns oo his wooden couch. The sensations produced 
by this operaUoD are agreeable, and are very far from producing 
that excessive redness of the surface described by Acerbi. 

The operator now anoints the whole body with a liquid mild 
aosp ; and, after again mounting to the upper tier for some time, 
we descend one by one to the middle of the floor, where a power- 
ful afiuston of cold water from ihe shower-bath in the ceiling re- 
moves every vestige of soap. This sudden a^'usion of cold wa- 
ter is remarkably grateful ; it is scarcely possible to describe the 
effect, which is highly exhilarating and refreshing. 

It is usual again to undergo the steaming after the tempera- 
ture of the bath is increased by the affuaon of water on the 
glowing pottery in the furnace. For this purpose, the opera- 
tor opens the door above described, and placing us out of the 
direction of the immediate efflux of the steam, he dashes, in suc- 
cessive jets, a small bucket of water into the furnace. The 
apartment is instantly 611ed with clouds of steam, at a high tem- 
perature i and when the door of the aperture as closed, we re- 
sume our places on the benches, gradually proceeding to the 
highest, OS we become inured to the temperature. From the 
upper tier we finally descend to have the cold shower-bath re- 
peated ; af^er which we leave the bathing-room, are rubbed dry 
by asnstants in the small heated apartment, where we resume 
the flannel dressing-gown and slippers, and are reconducted to 
the saloon, where we find the couches spread with blankets ; 
and we recline for half an hour in a most profuse perspiration, 
and in a state of luxurious Unguor, and mental tranquility. 

On a subsequent occaMon, I provided myself with the means 
of ascert^ning the temperature of the bathing-rooo), and noted 
its effect on the pulse of myself and two other bathers. The 
heat is generally from 45° to 50° of Reaumur ; that is, from 
133°.S5 to 14<4°.5 of Fahrenheit On the occasion referred to, 
it ranged in the bath, during my stay, from 42° to 46° R., = 
126°.5 and 135°.5 F. in the lower part of the bathing-room; 
but I was unable to examine the temperature near the ceiling, 
on account of the thick vapour, and the intensity (tf the tempera-

ture, which afi^cted my eyea. This t«nperKture, h^h as it is, 
is far short of what Acerbi asicrts of the FiDiuah baths ; he says 
that they reached from tOP to 76° of Celrius, = to IfiS" to 16T 
of our scale : but perhaps his tb^rmonctcrs were subject to the 
influence of the open firp-ploce in the rude bothsof that pco[de; 
for their furnace coneisted of s few loose stones pieA tato a sort 
of rude arch, over a fire on the floor of the hut : or perhaps he 
did not accurately ascertain the temperature ; as he never en- 
tered the bath but momentarily, for the purpose of pladng his 
theriDOiDeter ; and I am confirmed in (his by observing that the 
Finnish operator, in his ^axe, appears dressed in her ordinary 
clotheS) which I ^ould think insupportablG in so high a tempe- 
rature as he assigns. 

The eflect of the Russian vapour-bath is to accelerate the 
pulse, which soon r^iuns its natural standard on leaving the 
bath ; and, when I took it in a highly feverish state, I was with- 
in an hour after entirely free of fever, and abie fully to enjoy 
th« philosophic soir^ that evening. 

On bathing a second time, I was accompanied by the same 
two friends : our pulsen were befoir about 74 in a minute. On 
just coming out of the bath,

These experiments shew the great difference in the excitabi-

had the gout it ranges &om 74 to 80, but is very et^ily ex> 
dted; and I have often found it riused to more than 90 by an 
interesting conversation, or even a cup of stnmg tea.

sumed OUT drees, and retired to a coffee-rocHn, where there was 
a jdentiful supply of newspapers, and had a cup of good eo^e 
for twopence Sterling. As I have already stated, the baths 
were free to the nalur/bracher ; but I ascertained that the whole 
expense <^ the bath and its accompaniments is not more than 
one marc, or sixteenpenee English, and fat twopence more the 
ba^er is entitled to a cup of co^e, and to read the newspapers 
in a handsome apartment. 

I received from the liberal owner pennission to examine his 
sfJendid establishment of vapour and shower baths devoted to 
females. 

The vapour-bath resembles that already described, but is 
much neater. 

The variety of shower-baths surprised me. They are of 
every coneeivaMe toTta, from the powerful stream to the mi- 
nute drizxing of water from orifices as fine as a needle, which 
jet tiny streams of warm w cold water, at the option of the 
bather, in every pos^ble directioD on her person. By means of 
policed brass arms, curved so as to enclose the body, move^e 
by universal joints, connected with a cistern, and perfixated with 
inoumerabJe minute holes, a crogg^re of jets (if I may be al- 
lowed the expresdon) is kept up on any part of the body. If 
the bather inclines to sit, a perforated seat is placed on a tai^ 
flat trough, which collects and carries, off the water, jets of wa- 
ter play from the various moveable arms from each side, from 
above, and from below, so that every part of the snrfoce is be-, 
dewed. A general stopcock (ximmands the whole flow of wai 
ter, while each brazen-rod is under the control of one appro- 
priate to itself. These are at the disposal of the bather ; and 
each trough or bath is surrounded by curtains' to dcreen the 
person from the eyes of the as^stont. 

Similar shower-baths are appropriated to gentlemen. The 
whole forms one of the most elegant and perfect estaUishmenta 
<^ the kind I have ever seen, and is a som-ce of emolument to 
the spirted proprietor. 

I inquired anxiously into the medical efficacy of die Ruann

ness of limbs consequent on gout, and other Lpi^ cootiaued in- 
flwnmaliona, in some caaes of paUy, in various cutaneous dift- 
ea^es, it is a most powerful and valuable reipedy. While in the

I have described, be could walk alone as well as I saw him (he 
had walked, luded by a stick, from his house to the bath), and 
appeared confident that in a little time he should entirely re. 
cover the power and flexibility of his limbs. 

From all I could learn in Hamburgh, I am inclined to consi-' 
der the Russian vapour-bath as a most valuable remedy in some 
chronic diseases, and regret that we have not a simiUr e^tablish- 
ment in any of our medical charitable institutions.

On the Breeding Spots of Birds. By Fbederick Fabkh.* 

Xhe learned editor of the interesting Travels of M- Boie iu 
Norway, considers it as indispensable, for the complete deve- 
lopment of the eggs, that they ccmie in contact with the exterwd 
skin of the bird. This is certainly the case ; but I doubt very 
much if it is the reason of their plucking the feathers off thrir 
belly. Some water-birds, as the different species of Coiymbm, 
preserve the same dense mass of feathers on their belly during 
breeding, as at other seasons. Most birds, however, at this 
period have a much thinner covering on their abdomen than 
usual, and this is produced, in my opinion, partly by the fric- 
tion of hatching, partly by the excess of animal warmth which 
is CMcentrated in that region. The female of the Iceland grous, 
and of many wading birds, have the breast and belly nearly 
quite bare while breeding. But this falling out of the fcadiers 
is a consequence of hatching, and belongs to the next period. 
Aji «itirely different relation takes place among some of the 
boreal aquatic and wading birds. These pluck off a number

of feathers from one or moie spots of the belly on the develop- 
ment of the pairing impulse, and before they have Wd any eggs. 
Of have b^un to hatch. This gives rise to certain naked BpMs, 
which I call BrVeeRng spots. The utility of this arrangement 
is various. There is generally so thick a layer of feathers upon 
the belly of most aquatic birds, that without some process of this 
kind, the eggs would hardly ever be brought directly in contact 
with the skin of the mother. In the second place,. most aquatic 
birds have no nest, or other means of furnishing warmth to their 
*ggs, even in the coldest climates. The breeding spots thus 
form as it were a nest on the body of the parents, as they collect 
with their bills all tlie eggs into this artificial cavity, so that they 
are quite surrounded by the feathers. 

The discovery of this peculiar phenomenon in the history of 
the bcff«al birds is entirely my own. Only occasionally do we 
find former writers directing our attention to these breeding spots, 
but none seem to have recognised their real importance. Bang ' 
only found in the boreal birds, the discovery was reserved for 
a naturalist who had an opportunity of spending the summer in 
their native haunts. Gunnerus remarks of the ProceUaria gla- 
ciaiia*, that he had found no such cavity, but that the n:>ediCRl 
student Martin bad observed-|- them to possess a hole under the 
cn^ beneath the lai^ feathers, which he thought might per- 
haps serve for the hatching of eggs. Fabricius remarks, also of 
this Hid J. that he had found this hollow ; his words are, Jretun 
deplumem sub abdomine eiiam reperi. M. Brae Imb observed, 
ID his Travels (p. 192), which were written at the fiame time 
with my Prodromus, With respect to the Lestris parasiHc'a, thsft 
thisbird lays only two eggs, and shews that the two pbrenta, 
which sit alternately, have on both aides of the belly a naked

Therefore, we do not find in the nest the feathers wUch have 
be«i taken off the body of the bird. It is nece»ary tbat a por-

order that the eg^ come into immediate contact with the epi-

however, be thrir only use, because they are wanting in many 
of the aquatic birds of the cunpound nKMM^ray, whose coat of 
feathers, as just mentioned, is no thinner, as in the Suta and 
Carbo. They must, therefoFe, be intended to envelope and fur- 
nish the eggs with warmth. 

I have found these breeding spots only in the boreal aquatic 
birds, and confined to those species which helof^ to the po'feot 
»r compound monogamy. It would be extremdy interesting if 
tb^r existwce could be established in the aquatic birds of other 
KHtes *. They are never found in the genera Cohfmbus and /V 
dkeps, which belong to the partial monc^anay. They are equally 
wantjog in those «mply mc»x>gatnooB, as the Mergtu, Anas, 
Anaer, C^gnus. But idi these birds have the habit of ptuckii^ 
out their feathers for the pui^xMe of limng their nests, which 
does not exist in those fMrde which behxig to the perfect nmaa- 
gamy, such as the Phaiarepus, Uria, Alca, Mormon^ Carbo, 
P»iffiMU3, Suia, Sterna, Lanta, Lettris, and Procellaria. Breed- 
ing ^wts are found in all th^se genera, with the exception of the 
Svla and Carbo. 

As both male and fem^ of ibece species share the labours of 
hatching, the breeding-spots are found in both sexes, with tbe 
remarkable exception, however, of the Phaiarepus, where they 
exist only in the nale f. Among the many hundred individuids

But I had befcM^ me at tiie time spedmens wiiiidi were only com-

tbeie di&dCDt fwtdies would have uuited into aaiagle one in the 
oemtSB a£ ibe abdooien, when it had assumed its fini^ed fonn. 
The P/udaropiu, Uria gryHe and alie, Alca tarda. Mormon 
fratercula, LestrU, have two breeding ^ts. The Uria brun- 
rucbU and treile, Fi^nta ardiau, Stenta oreAx, Larttt iri- 
4actf/lua, giauatt, marinua, and the PioceUana glacialu, iutve 
font one spot. One of the mott imptstant distinctiona betneen 
die .dica tarda and Uria troile attctorum is, that the former has 
two and the latter but one breading spot. 

In regard to posUioH, the^ an always on the belly, jiever oh 
the breast ; and when one only is present, it is condantly in the 
middle of the belly ; when two exist, they are eymmetrically on 
each ade. Their^/grm is circular and proportioned to the size 
and number of the f^gs wbioh diey have to cover. A central 
spot is always lar^r than each of a pair. 

Their DHmber occasioBBily corresponds to ihat a£ the eggs, 
Iwt aoinetiniea tbene are more eggs ^an spots, as in the Lanm .- 
in the Alca torda, and Mlornonf rater aiia, the iipots exceed tJke

are generally large, and capable of including more than a single 
e^. When the spots are more numerous than the eggs, these 
change their portion. 

from the deBciency of the breeding-apots in the Phataroput, a similar defect 
in the breeding impulse? This genus would then be a soHtar; exception, 
uf one iodividuxl lading the eggs, and another hatching them. It must, h«W'

34 M. Faber m the Breeding Spots. of Bmb. 

The Uria gryUe, Lettris caiarradet, pQmarma, and paroti- 
tica, have two eggs and two breedipg spots. Tbe Uria Awn- 
tKcAH and troile, Pt^nut arcticua, uid ProctSaria glackilvt 
have one e^ and one spot. The Uria (tile, AUa tordoy and 
Mormonjratercula, have but one egg aad,two breeding appta. 

The P/uUaroptu cinereta, and Pla^hmchus, la; four.fggl^ 
and have but two breeding spots. The Sterna arctita, Lanu 
glaucua, marmui, and tridachflua, have scwnetiioes tbreei some> 
tknes two e^a, but constantly only one breeding spot. 

These spots are not endrely meant to supply the place <4 a 
nest ; they are, there&re, not invariably in an invene ratio to 
the building impulse. Certainly, tbe species which want theae 
spots, as the S»la and Carbo, build a D^t ; most of those, also, 
which are provided with them build no nest, as tbe Phaiarcputt 
Urioy Aka, Morindu, Ptiffima, Sterna, Les£ria, ProceSaria ; 
but the genus Lotus have breeding spots and build nests. 

Their presence is therefore merely a proof of the development 
of the pairing impulse, but is not to be considered as synony- 
mous with the laying of ^[gs or hatching. Birds pluck out these 
feathers before oven they have jtuned their mates, and without 
bmng certain of breeding that year. Therefore I have found 
them in May, in individuals of the Lestria catarractet, and Pro- 
ceUaria glacial, which were so far out at sea, and removed 
from the breeding places of the species, that I had good cause 
for reckoning these barren birds, which pass the summer with- 
out breeding. They also eicist in the single individuals of the 
Lestrii parasitica, which flock about together. 

AfWr hatching is over, these bare spots are very quickly 
again covered with feathers. All traces, of them have disap- 
peared in August and September, when the young of some 
speaes are not yet fledged. 



Analysis <^the Stony Pericarp (^ the LUJtospermum officinale. 
By Captain Chakles Li Hbstk. (Communicated by the 
Author.)

in the vegetable kingdom, its properties, mechanical and chemi- 
cal, are those of a mineral, rather than that of a vegetable. Tbe

heated, they at (irst become black ; but diey do not ^rink, nor 
does a' white heat change their form, in the ali^tett degree ; it 
destroys, however, tbe^ lustre, and renders them, when the ve- 
getable matter has been consumed, whiter than they were ctfi^. 
bally. Before- the blowpipe, sbiall pointed fragments of die 
pericarp may be partially fosed ; but ibia requires a gtxpd beat 

To deteitBine the naturt and quantity of the earthy consti. 
tuents, the pericarps were care&lly separated from the enclosed 
seeds, and exposed to the action of dilute muriatic acid ; a 
>k>lent effervescence immediately commenced, which did not 
enlJTdy cease for upwards of two hours. At the end of twelve 
hours, the acid liquor was decanted, and the pericarps were well 
washed. Their appearance was not in the least changed ; when 
diied, at a moderate heat, they still retained their original lustre. 
The acid liquor was found to contain a grrat deal of hme, a very 
little phosphate of lime and oxide of iron, with traces of potash 
and magnesia, which were separated in the usual manner. 

The pericarps were then heated to destroy the v^elable mat- 
ter, which it is exceedingly difficult to effect ; but, notwithstand- 
ing the intense heat employed, the form of the fragments was 
not changed by it, they merely lost their lustre, and became 
very white. When the vegetable matter was entirely consumed, 
they were again treated with muriatic add, and Mt in a warm 
place for several hours. The acid took up a vety little phoo- 
phate of lime and oxide of iron. The matter insoluble in the 
add, was fused with carbonate of soda, and found to be pure 
siltca. The analysis was repeated, and the compoation of the 
substance appeared to be very uniform. The following - is the

■On the VilalU^ of Toads enclosed in Stone and IVood. By tbe 
Rev. W. BocKtAND, F. R. 8., F. L. S.. F. G. S-, and Pro- 
lessor of Gedogy and Mineralogy in the Uoiverwty of Ox- 
ford. Communicated by the Author. 

In the moBtb of Nonember 1825, I commeuoed the fotlowing 
experiments with a view to expbun the frequent dieooveries of 
toads enclosed within blocks of stone and wood, in cavities that 
are said to have no communication with the external ^r. 

Ib one large block of coarse oolitic limestone, (the Oxford 
oolite from tbe quarries of tieddington) twelve- circular cells 
were prepared, each about one foot deep and five inches in dia- 
meter, and having a groove or shoulder at its upper margin fitted 
to rec»ve a circular plate of glass, and a drcular slate, to pro- 
tect the glass ; the margin of this double cover was closed round, 
. aHd rendered impenetrable to air and water by a lutit^ of soft

clay. Twelve ensller cdls, each six uches deep aad five inches 
io dianieter, were made in aootber block'of compact tilicaBua 
ssndshtne, vi>. die FcDnuit Grit of the Coal tottatlUan near 
Bintol ; these oeHs aho were covered widi niailar piatea «f 
^ass and «late ceaieated at the edge by eky. I^e al^ect of 
the glass coven was to allow the animals to be inapecCed, wtdw 
out (baturbing tbe clay so aa to admit external air or imeoto in- 
to the ceU. Tbe limestone is bo porous durt it is easily peme- 
aible by water, and probably also by air ; the sandstone u very 
compact. 

On tbe !i6th of November 16SS, one live toad was phuied in 
each"of tbe idiove-ineationed twenty-four oella, and the double 
eoKT of glass and slate jdaced over each of them and cemented 
down by tbe luttog of clay ; the weij^ of each toad in gruns 
was ascertained and noted by Dr Daubeny and Mr Dillwyu, at 
die time of their being [daced in the oells ; that of the smallest 
was 115 grains, and of the largest 1185 grains. The large and 
small aimnalB were distributed in equal prc^Hntion between tbe 
4iinestone and the sandstone cells. 

These blocks of stone were buried tt^tber in my gardes 
beneath tlu^ee feet of earth, and remained unopened until tbe 
lOtfac^DecenberlSSd, on which day they wereexamined. Every 
toad in the smaller cells of the compact sandstone was dead, and 
the bodies of most ai them so much decayed, that they muA 
have been dead some months. The greater number of those 
in the larger oells of porous lunestooe were alive. No. 1, whose 
wei^t when immured was 924 grains, now weighed only 698 
gruas. No. S, whose weight when immured was 1165 grains, 
now weighed 1965 grains. The glass cover over this cdl was 
slightly cracked, so that minute insects might have entered ; 
none, howevo-, were discovered in l^is c^l ; but in another cell, 
whose glass was broken, and the animal within it dead, dieie 
was a lar^ assemblage of minute insects, and a simUar anem- 
hlage also on the outside of the fj^ass of a thisd o^ In tbe 
cell No. 9, a toad which, when put in, weighed 988 graaaa, bad 
increased to 1116 grains, and the glass over it was entice ; but 
as tbe luring of the c«U widiin which tlus toad had iocreaacd in 
weight was not pwtioularly examined, it is probable there was 
sMne aperture in it, by which small insect* found adminioa. 
No. 11 had decreased from 986 gndas to 6fi« grains. 



fS Rev. Dr BuckUnd m th€ VUaHt^ of 

When they.«eK first ezanuned in Deoonber 1SS6, not onty 
were all tbe bhioII toads deail, but the larger ones appeAred 
much emaciated, with the two exceptions above mentioned; We 
have already tUted that tbeae proboUy ow«d tfeeir indraaed 
weight to the insects which had found access to the ceRs asd 
become their fixxi. 

The death of every individual of every siae in tbe ximiMer 
cells of compact sandstooe, appears to have resisted from a dew 
ficieney in the supply of air, in consequence of the sm^htess of 
the cells, and the impermeable nature of the stone ; the larger 
volume of air ori^nally enclosed in the cells of tbe limestose, 
and the poraus nature of tins -stone itself (permeable as it is 
alonJy by water and prc^Ntbly also by air) seems to have-fhvoiir- 
ed the duration of life to the snimols enclosed in them withoift 
tood. 

Jl should be noticed that there is a defect in these expert- 
nents, aiinng bom the treatmeat of tbe twenty-four toads be- 
fore they were enclosed in the blocks of stone. They were shut 
up and buried on the S6th of November, but the greater num- 
ber of them had been caught more than two months before that 
time, and had been imprisoned altogether in a cucumber frame 
|daoed on common garden earth, where the lupply of food to so 
many individuals was prohaUy scanty, and their confinement 
unnatural, so that they were in an unhealthy and somewhat 
meagre state at the iitae of tbeir imprisoDment. We can there- 
fore scarcely argue with certainty from the death of all these 
individuals within two years, as to the duraticm of life vHbh 
imght have been maintained had they retired spontaneously and 
&Ucn into the torpor of their natural hybernisation in good 
bodily condition. 

The results of our experiments amount to this ; il\ the toads

Before the expiration of the second year, all the Urge on^s alaO

deepaad three incbea in diameter; they werecaiefully dosed vp 
with a plug of wood, so as to exchide asoess of insects, and 
apparently were aii-tight ; when racamined at the end <^ a yeu*, 
evary one of the toads was dead and their bodies were, decayed^ 

FnHD the fatal result of the ezperinunts made in the smalt 
cells cut in the apple tree, and the Uock of compact sandstone, 
it seemB to follow that toads cannot live a year excluded totally 
from atmospheric tur ; and from the Kxpaimeots in t^e larger 
cells within the block of oolite limestone, it bcqisb probable (hart 
they cannot survive two years entirely exduded froni food ; we 
may therefore conclude, that there is a waat of sufficiently mi- 
nutewd accurate observation in those so Irequ^tiy recorded 
cases^ where toads are said to be found alive within blocks ctf 
stone and wood, in cavities that bad DocoDimuitioation whate««c 
with the external air. The fact of my two toads having in- 
creased in weight at the end of a year, notwithstanding the care 
that was taken to eneloee th«n perfectly by a luting of i^y, 
shews how very anall an aperture will admit minute insects suffi- 
cient to munlain life. In the cell No. 5, where the glass was 
slightly cracked, the communication thovgb small waa obvious-; 
but, in the cell No. 9) where the glass co w mnaiiMd enlirei and 
where it appears certain, from the increased weight of lite endosd 
animal, that insects must h&ve found adisisuon, wt:hafv« an 'ex- 
ample of these minute animals 6DdiDg their way: into a cell, to 
which great care bad been tgkea to .prevent any |x)BsibiliCy of 
access. ., . 

Admitting, then, that toads are ^ccowmioUy found in cavities 
of wood and stone, with which: there is no communicatioa suffi- 
dently Urge to allow the iognew and egress of the animal en- 
closed in them, we may, I think, find a solution c^suoh phene- 
mena in the halnts of these r^tilei, aad of the insects .which 
form their food. The fir^t effort of the ywing toadj as soon as

k basleft it» tadpole state and emerged from the water, is to 
seek sbelter io bdbes «nd crences di rocks and tree*. Ad indi' 
vidua], which, when young, may have tJius entered a cavity by 
80ne very ntfrow aperture, woold find abundaBce of food by 
catching insects, whicb like ksdf seek shelter within such can- 
ties, and may bood hare increased so much in bulk aa to render 
it tmposable to go out f^ain, through the narrow ap«ture at 
which it eotwed. A small hole of this kind is very likely to be 
overlooked by common wt^kmen, wboare Ibeoidy people wbose 
(^leratioiM on stcon and wood disclose cavities in the interior of 
sudi subetaDces. In the case of toads, snakes, and lizards, that 
OGCasiaii^ly issue from stones that «k Int^en in a quarry, or in 
siniting wdls, and sometimes even from strata of coal at the bot- 
tom of a cool mine, the evidence is never perfect to shew that 
tbe reptiles w«e entirely enclosed in a solid rock ; no examina- 
uoo is flv^ made until the re|)tile is first discovered by the 
bret^ng of tbe mass in which it was contained, and then it is 
too late toascertain without carefully Tefdacing every fragment 
(and in no case that I have seen reported has this ever be«l' 
drnie) whether ix not there was any kcde or crevice by which 
tbe animal may have entered the cavity from which it was ex- 
ttacted. Without previous examination it is almost impossible 
to prove that there was no snch communieation. In the case of 
rocks near tbe surface of the earth, and in stone quarries, rep^ 
tilea find ready admission to hides and fissures. We have a no- 
torious example of this kind in tbe lizard found in a chalk pit, 
and brought alive to tlie late Cr Clarke. In the case also of 
wdls and coal pits, a reptile that bad fallen down the well or 
shaft, and survived its fall, would seek its natural retreat in 
tbe first hole or uevice it could find, and the miner dislodging 
it from this cavity to which his previous attention had not been 
called, might in ignorance conclude that the animal was coeval 
with the stone fromwhich he had extracted it. 

It remuns only to consider the case, (of which I know not 
any aathraticated example), of toads that have been sud to 
be found in cavities within blocks of limestone to which, on care- 
ful examination, no access whatever could be discovered, and 
where tbe animal was absolutely and entirely closed up with 
stone. Should any siiolv case ever harve existed, it is [MTobidile 
that the oommuniatlioD between this cavity fuid the external 



Toads meioted in. Stone and Wood. SI 

surfdce had beea closed up by stakctibc tncruBtetion after tb* 
animal had beeome too large to umk* ita tacapt. A simUar ex- 
planation loa; be oSered of the much more probaUe caae of a 
live toad haiag entirely surrounded with st^id wood. In each 
case the animal would have continued to mcreate ia bulk to 
long as the smallest aperture remained by which air and insecta 
could fifid admisMoa ; it would [H-ob^y beeome tn^ad as sooo 
as thie aperture was entirely closed by the accumulaUon of stal- 
actite or the growth of wcmd ; but it still remains to be ascertained 
how long this state of torpor may continue under total exdu- 
Hon from food, and from external air : and altbougfa the experi- 
ments above recorded shew that life did not esteod two years 
in the case of any one of the individuals which formed the ■ub> 
jec.t8 of them, yet, for reasons which have been specilied, they 
are not decisive to shew that a state of torpor, ot svepended ani- 
mation, may not be endured for a much longer time by toads 
that are healthy and well fed up, to the mom^t when they are 
finally cut off firom food, and from all direct accesa to atmcapbe- 
licmr. 

The common experiment of burying a toad in a flcmer-pot 
covered with a tile, is of no value, unless the cover be carefully 
luted to the pot, and the hole at tbe bottom of the pot ^so 
closed, so as to exclude all possible access of air, earthworms 
and insects. I have heard of two or three experiments of this 
kind, in which these precautions have not been taken, and in 
wlucb, at the end of a ytat, the toads have been found alive and 
well. 

Besides the toads enclosed in stone aiKl wood, four others 
were placed each in a small baun of plaster of Paris, four inches 
deep and live inches in diameter, having a cover of the same ma- 
terial carefully luted round with ctay ; these were buried at the 
same time and in the same place with the blocks of stone, and 
on bdng examined at tbe same time with them in December, 
18^, two of the toads were dead, the other two alive, but much 
emaciated. We can only collect from this experiment, that a 
thin plate of plaster of Paris is permeable to air in a suflvnent 
degree to maintain the life of a toad tor thirteen months. 

In the I9th Vol. No. 1, p. 167, of SillimWs American Jour- 
nd of Science and Artn, David Thomas, Esq. has published some 
observations on frogs and toade in- stone and soUd earth, enw-

but, they state not soy thing to disprove the possibility of * 
small aperture, by which these cavities may have had communi- 
cation with the external surface, and insects have been admitted. 

The atteudon of the discoverer is always directed more to the 
toad thau to the minutiae of the state of the cavity in which it 
was contained. 

In the Literary Gazette of March IS. 1881, p. 169, there 
is a very interesting account of the habits of a tame male toad, 
that was domesticated and carefully observed during almost two 
years by Mr F. C Hueenbeth. During two winters, from. 
November to March, he ate no food, though he did not become 
torpid, but grew thin and moved mudi less than at other times. 
During tbe winter of 18X8, he gradually lost his appetite and 
gradutJIy .recovered it. He was well fed during two summers, 
and after the end of the second winter, on the 29th of March,' 
18S9, he was found dead. His death was apparently caused 
by an unusually long coiiliiniance of severe weather, which 
seemed to exhaust him before' his natural appetite returned. 
He could not have died from starvatbn, for the day before his 
death he refused a lively fly. 

])r Townson also, tn his tracts on Katural History, fLondon 
1799), records a series of observations which he made on tame 
frogs, and also on some toadS; these were directed chielly"_ 
to the very aHiorbent pftwer of the skin oT these reptiles, aifd ' 
£bow that they take in alnd r<ject' liqtiids, through their skm . 
alone, by a. rapid process of absorption and evaporation^ — a frc^ . 
absorUng sometimes tti h^f an' hour as much ashalf its own 
wMght, and in a few hours the whole of its oWn weight of wa- ' 
ter, and nearly as tafMly giving it off when plttbed in any posi- " 
tion that is warm and removed from moisture. Dr T. contends ' 
that as the fn^ tribe never drink water, this fluid niukt he sup- 
j^ed by tnemidof absorptiMi through the skm. Both frogs and " 
toads have a large bladder, >wlAch is flflen fontid full of water;

On t/ie Chm^icai Conttiiuiion iff Haxmotomty or Cratsstone. 
By Akthdk Cornell, Esq., F.R.S.E. Communicated by 
the Author •. 

In examining Bome spedment of harmotome from Strontian, I 
observed some crystals which appeared to present a very dif- 
ferent aspect from the ordinary barmotume with which they 
were assodated. The usual crystals of this mineral from the 
above locality are welt known to be of considerable me, and to 
exhibit the form of a rectangular [xisni, Plate I. Fig. 1, tennina- 
ted by a pyramid, the faces of which are set on the lateral edges of 
the prism, two opposite edges of the pyramid being also replaced 
Ity planes. Un the other hand, the crystals to which I have r& 
ferred were a great deal unaller in size, usually not exceedinj[ 
one-tenth of an inch in length, and of greater transparency ; 
uid they presented the apparently very dissimilar form of a 
rhombic prism, Fig. 3, of considerable acuteness, having the 
acute angle more or less truncated by the face A, and termi- 
nated by a pyramid 0, ibe faces of which were set on the lat&- 
ral planes of the prism, and its apex truncated. . They were' 
spread over the surface of calcareous spar in considerable num^ 
bers, and were usually atUched to the matiix by one of the ex- 
tremities lyD. Farther consideration, however, showed that 
this latter form wqs in reality merely a modiBcation, although 
undoubtedly a very conaderable one, of the old form, and 
arose principally from the vertical contraction gf the crystal. 
Fig. 1, and its borizootal dongation in the directioi^ of the faces 
BB', the inclination of the several faces to one another remwit- 
ing always the same; as will be evidrat by comparing F^rea 
1, 3, and 3, Fig. 3 representinganotberformof thcicrystal, whicll 
may be r^arded as intermediate between Figs.'! aqd^, and the 
whole three being placed in- parallel position, with their eorret- 
ponding faces marked by the same tetters. In some rare in- 
stances, the pynamids C C, and the face A, Fig. 8, alnwst en- 
tirdy disappear, so that the crystal spears newly as a eimpla 
riiombic prism; and in others equally. rar^ the face D almost 
disappears, so as to leave the pyramid.nearly without truncation.

94 On the Cheptical CoTtttitution ofHarptetfim^ 

A few minor modifications of both forms also occur, vhich it fs 

unnecessarj to notice. 

I was farther confirmed in these views of* the conneipon be- 
tween the two forms, by the opportunity which the liberality 
of Mr Allan afforded me of consulting the interesting catalogue 
of his collectJon, drawn up by Mr Haidinger, in which I found 
a series of figures of hannotome crystals, presenting, in so far 
as I cbuld judge, a transition of the one form into the other, 
with some of those lesser modifications to which I have alluded. 

As the angle of the faces B, replacing the opposite edg;es if 
thepyraraidinFig.l, has been stated by Mr Phillips as 110° 86*, 
this will of course become the measure of the' rhombic prism. 
Fig. 3, if the foregoing views of the relation between the two 
finiDB are correct. ' 

Before the connexion of the two forms Tigi. 1 aad S had oc- 
curred to me, which was not until I had obsraved « crystal of 
^e form Fig. S, I camnienced an analysis of a portion of (he 
crystals of the rhombic form, Fig. 3, under the idea that they 
might present some modification of the usual constitution t^ 
this mineral ; and although they proved to be merely a baiytie 
barmotome, yet the analyus seems to throw some little addi- 
tional light on the connexion between the barytic and lime va- 
rieties of the mineral. The steps'of the analysts were as followa 

(a.) 7.87 •grains of the crystals in coarse powder Imt, by ig- 
nition, 1.1 grain, equivalent to a loss of 14.9!t5 pa* cent 

(6.) 16.07 gr^ns of the crystals whbli bad been previously 
treated with addulated water, to remove all adhering calcsreouft 
spar, were reduced to impalpable powder,' and then left for thiek 
or four days in contact with muriatic and, a moderate heat beitifj 
octssionally applied. Tile mass did not gelatinize ; but, as w9! 
afterwards appear, the action was quite sufficient fitr the purpose 
of analysis. The whole was evaporated to dtynesa. A littla 
muriatic acid was then poured over it, and left for some Hourtj 
when water was added, and heat applied. The silica was ibrtt 
eeparated by filtrtttim. After ignition, it wngfaed 7.fi5 gr^ns: 
It dissolved in boiling caustic pota^ ley, except b' residue df 
,47; whicb was rcsolv^ by fiinoo with cartxwated alkalies,' ann 
other necessary steps, into .4 of silica, and .01 of oxide <^ iron. 
The total siUca thus amounts to 7.48 grwns.

I may take thia opportunity of tnentioning, that after I bad 
detected alkalies in barytic harmptotne, i( occurred to me to ex- 
amine Brewat^te again for alkalies by tlie same process, wbich 
was applied to the foriper mineral ; my previous researdies for 
alkalies in Brewsterite bavipg been made by decomposing it by 
carbonate of baryta, and throwing down the baryta by carbon- 
ate of ammonia, a method which renders necessary the ultimate 
expulsion by heat of a very large quantity of ammoniacal Bait, 
which is apt to carry along with it small quantities of fixed chlo- 
. rides. I accordingly treated a small quantity of powdered Brew- 
sterite with muriatic acid, lea^ng them in contact for some dayi, 
and occa^onally applying heat. By the process already detaS- 
ed, I ultimately obt^ned a minute quantity of cubical crystals'; 
and, on examining those by muriate of platintitn, tfavj beeAed 
to be entirely chloride of sodium, at least operating with the 
small quantity of materials wbich I used, I could not detect 
potash. Tfae minute quantity of soda is of course in sdditiwi 
to fitrontia, baryta, and the other constituents whidi I formerly 
mentioned in Brewsterite, When my time permits, I tntendto 
execute another analysis of tlie mineral, lo ascertain the exaict 
proportion of alkali i( contains. -.;-- -

Remarks on some of Baron Cuvier's Lectwrei on the History

— iedg&<^ the Egt^aiaas i of the source from rehence Afoies 

■ derived hie GosmogfMy,.and the genervi agreement ^ that' 

Cosmogony with Modem Geology '". ■ 

Ik Bome of the Numbers of theEdinburgh New Philosophical 
Journal published in lUSO, are given Reports of Lectures an 
the History of the Natural Sciences hy Barou Cuvier ; aud in' 
psgps 342, No. XVI,, we find in them the following statement' 
respecting the Hebrew legislator : — '* His books shew us, that 
he had very perfect ideas respecting several of the highest ques-] 
.tioDS of. natural philosophy. Hia cosmogony especially, conu-, 
dered in a purely scientific view, is extremely remarkably inas-. 
.much as the order which it assigns to the different epochs of 
creation, is precisely the same as that which has been deduced 
'ft-bWgeOtogital conaiderations." This, then, is the issue, in the 
opinioD of Baron Cuvier, of that science, which has been held 
by many persons to teach conclusions at variance with' the 
Book of Genesis, — when at last more matured by a series of 
careful observations and legitimate induction, it teaches us pre. 
dsely what Mtwes had taught more than three thousand years ago. 
But at the same time that, the Baron makes this stateiiiehl, it 
is implied by him in the accompanying sentences, that the'He- 
brew legislator had acquired his knowledge of Ihe cosmogony 
from the Egyptians ; for lie says, " The leaders of the colonies 
which issued from. Egypt possessed, in general, but a small 
part of the knowledge of which the pnvileged caste (the priests) 
was the depositary. They carried with tliem only the practi- 
cal results. The case was different with the 'JHebrew legislator.

The preausGB from which it is inferred that the Egyptiab 
priests may have possessed such a knowledge of geology as 
would f urviBh a foundation for the cosnu^ny of Moses, are liy 
much too meagre to warrant such a concluaon. The chief of 
them u indeed found in what Herodotus states regarding the 
land of the Delta, by depositions from the waters of the Nile. 
It is said in page 340, " The Egyptians I»d very conwct ideas 
on several pomtg in geology ; they had well (^nerved the laws 
o( alluvial deposition, and at the present day we account t<x the 
^Jnoatioor of the Delta m no other nuuiner than that in winch It 
WW accounted ior in the days <^ Herodotus." 

In turning to Herodotus, reelecting wbtan many modem dis- 
oovenes have pro¥ed that be Was a futhful chronicler of what' 
he satr, although often absurdly credulous of the reports of 
ofbsrs, we fiad no {Roof in bis relotioa, tfiat the Egyptians had 
weU dxcrved the &mr of idluviol depotdtiog. With respect to- 
the prjesta, be st^et, in the passage referred to by fhe Barotr, 
4}l^y that th^ informed Ihbi of two faCts ; one, that the greater' 
pwrtt^AcDUDtcy, of wluch he describes the limits was an sddi- 
tHHi of land to the Egyptkasby the depositions of the Nile; 
the other, that in the rdgn t£ Myris, about nine hundred years 
before the time of the liistorian, the land was so low, that if the 
rivet rose to the hdght of eight cubits, it was sufficiently wa^ 
t»ed ; whereas at tlie time he vinted Egypt, tinless tHe river 
r^K fifteen or sixteen cubits the land was not sufficiently w«-' 
Ured. Thifl i> not scuoee, but faiatatyi Ifo reasoning of did 
priests is addol wMi regard' to ^esK sim^eftetst andtheevi^ 
^nce appears ctMiclusive, that 'he'h'Ad heard no' reaching dP

histonap nearest the time gf that oppression to which the ^ 
oerdatol caite was subjected by Cambyses. Had it been of tha^ 
terrible and exterminating character that would liave^ involveil, 
the loss of their science, we should certainly have had from that 
historian a more full account of it ; for he expresses great dis-> 
approbation of the Persian king for deriding religious institu- 
tions, and has given a very detailed and graphic account of th^ 
king's madness, and of his murders of many of his own Per. 
aisDs and relations. 

The time that Cambysea remained' in Egypt after the mti- 
dent of the god A^ns, was too short to admit of any extenave 
extennination of the priests and their science; for his whole 
rdga was only seven years and five .months, moet of .which nutsi 
bare beeo coosumed ia the negoctationsaod |ff«parations that 
preceded Ins Egyptian wu-, and the carApaigns he made, in- 
cluding the delay occasioned by his embassy to the M aerobians 

Accordingly, Herodotus himself Soda tha priests still in full 
po^aeasioa of their sacerdotal authority, and all l»«Dches at the ' 
EgypUoo- superstition flourishing in full v^ur. He describes 
many of their temples as seen by himself still standing, and the . 
scene of the same degrading rites to which ihey were origtnaUy 
deeped ; -and, the priests could y«t. shew bintho.spaciouB 
buildti^«hidi contaifled tha iifti^es of all the high priests, from 
father to son, and could repeat their genealogies. Besides this, 
the priests were yet in possesion of an accurate outline account , 
of ^opie part of the Egyptian history preceding the ika* e£ ■ 
Cambyses, as is evident from the gdod agreement, h) pcnntc^ "

'It is'alMgether.incre(lil>le, that, while their superstition and 
IristorjT thus ^grvived the persecution of CvnbyEes, th^r scieoce 
shoultl have been utterly lost. There can be do question that 
it'toO. survived,. such as it vtfls; and, r^ardingits true quality, 
the ^tuQe inquisitive historian has furnished us with very con^- 
derable'5l)formation. Thus, for instance, at his enteripg on tb« 
subject of Egypt, he puts us in possession of the true merits of 
their experimental philosophy, in the story, of the two infante 
p«rt, tban an that of the latter part Now, in reckoning bsckwiirds&oiD Sethcm 
of Egjpt and He^kiah of Judah, who were both contemporary with Saailn^ 
cherib, «e find eleven Ungg of £gjpt ioduBirelj to SesosCria, and twelve 
lunga of Judah to Reboboam, who was contemporary with Shisbak. 

la estimating the merits of the pgsitJsn that Sesoatiia and SMshil (ui the 
iqituagint Sgus^im) are the same, it is a matter of no small moflient that 
tke first s^llBbles of the respective names aiecomposedof letter* of the same 
origin, espe<:iall/ as we find a similar circumBtaDce taking place n^rding the 
name of another Egyptian king, mentioned both by Herodotus and the Jew- 
ish hlstcirians ; Ibe Sethon of Herodotus being evidently no other than So 
(or, independently of the lUCasoretic points, Sua), hi, 3d Knge, xvii 4, whii^ 
■ibe sepbia^l has changed to Segor. 

There &re several cbcumstances In Which, there are ah|igul*r agreemente 
between the details 'regarding Sesostria and Shishak. Herodotus tells ui, 
that wEen Sesostrii met with a brave reristance on the part of any nation, 
he erected honorary coIuouib to commemorate their leaohitloD, and whea he 
was - opposed by any people ia a cowaidly manna', hp ereotod cotarnDs with 
marks of inftmy upon them. He tells us, also, that he himself saw aome of 
these colitmos of the latter sort in the Syrian Palestine, of which country we 
elsewhere learn from him tte city Hadytis, or Jerusalem, was the capital ; 
-and on referring to the luatDT; of Shishak, im find that be was permitted to 
■^under Jeiinsalem without resistance, 

. The oonquetta <rf Sesostcia and Sbishak agree also Im reified, of their tem- 
jwiary character. Neither of them ia described as attempting to keep per- 
maatntpoaieiElon of the countries he subdued,.^^ very remarkable drcum- 
Rt^K^ almost unexampled in the history of cunqu^ors. 

The people named as fbrmitiig the acmies oC Slushak i^ree weU vitti what -

Refined coincidences of aits and institutions of some ancient ntt', 
tioDs, aod some acknowledged agreeipentg in their languages, to 
Yfbich we shall now. direct our attention. 

. JnJ4q. .16, p. 9^1, we are informed: " It is in India, accord-; 
ii^g to. all appearance, that we are to look for the origiit of thc^

Itriority of the Indians, is ftu-lher shewn by a tradition to which 
ao atteoticHi seem^ bitbqito to have been paid. It is, in fact, in 
Ihe Gxtracte which have been preserved of the works of Mane-_ 
tho, that, in tbe teigo <of Anient^his, a king of the l6th dynasty, 
a colony came, from India to settle- in Ethiopia. , Now Diodorua 
Siculus, and all those who have written on the religion of Egypt^ 
derive that religion from Ethiopia, or Upper Nubia. Thebes 
itself was but an island, a colony of Meroe, which was the sacer-t 
dptal.rity of the Ethiopians. Thus, then, civilization came from 
India 'vat» Nubia, and from Nubia into l^gypt.'" We ace then 
inftx-med, that among the Indians themselves we find no account^ 
of the progress of sci«ice, which is conjectured to be owing to 
tbe doctrinal point of the Brahmins, that hbtory should not be 
written, although, in the case of Egypt, the conjecture had 
been, that science had been uttjerly Itwt^ while we found hiatory 
in some measure preserved. We then have a notice of the In- 
dian monuments, which are acknowledged not to be very an- 
d^rit; and of'lheir most andent books, the Vedas and Oupa-

Ssiovee there 'highly «atiahcti»y internal evidences that he dM 
Hot, and to some of these ire shall mw direct our attention. 

"Th^ 'first chapter of Oenens is Written in a- pure Hebrew. 
This' wa6 ffaef tatigoage spoken, and afterwards extetisirely mit- 
ten, bjr the people whomMoHea conducted to Falestiaefrot^ die 
land of^Odshen. That ft d(fl^*«^ gnMiy from the labgu^ of 
ttefe'EgyptlanB, we have full probf in tlie Coptic ifemains of 'the 
tatter, in the Egypti^ ^pet nata^ preserved in the Hebrew 
writings, and also in'the circumstance that Joseph, when pre- 
teiiding to "be an Egyptian, conversed with his brethren by means 
of an interpreter. Yet, in the chapter tn qu^tion, ve ifind do 
ibreign terms, no appearance of its being translated from ai^ 
other tongue ; but, on the cotitrary, it bears every internal mark 
of being purely original, for the style is condensed' and idioma- 
lical in the very hi^esi degree. Bad Moses derived hisscience 
from' Egypt) either by' oral commuQicadon, or the study of 
Egyptian writlogs, it is Inconceivable that some of his terms, or . 
tbie 8^1e of his com[)osition, should not, in some point or oth^, 
betn^ the plagiary or copyist. ' 

' But the cbnjcicture that MoseS borrowed his cosAiogony from 
tfiS Egj'j>tiUis, mdst'test, moreover, on a supposition that the 
(trdei* which ' he aasigna fbr the diSerent epochs of creation had 
bet^ deteriiiined by a course of observation and induction, ai^ 
Ae ooirect application of niahy other highly pei;ftcted sciences 
to the iUostration of the subject, equal at least in their accuracy 
dlid' 'pfitlbsophiCa'I precision to those by which our prefent geo- 
logical knbi^leijge has been obtained. Nothing less than tWs 
can account for Moses' teaching us pirecisely what the modem 
geJibtgy te8ch«i,1f we' allow his knowledge'to be merely hubidn.

and satisfactory results, be baa Jtteeo enabled so totaU; to e:(clud«.. 
fro(n his record every, trace of the «eps hj which they were .-ob- . 
tained ? The suppoEititqi of such perfection of geological k^ov-v 
Ifudge in aDcient £gypt, implies a Jong series of observation, by, 
many individuals having thi^. same. object in view. Jt implies of. 
necessity, also, the iavention and use of many defined terq)B, i^f 
Bi^euce, without which there could have beenjio mutual jiodtf- 
standing among the ditTerent observers, and of course no pro?^ 
gr«BB in their pursuit. These terms have all totally disappeared 
in th.e hands of Moses. He has tiynslated, with precision, jthe 
whole sfuence of getdogy into the language of i^epberds and 
hu^jandoien, leaving no trace wha^ver of any .one.<^ its pecu- 
liar tprms any. mcs'e than of the curious steps in its- progress. ^ 

But there is a phenomenon in his record sullmore uDacc«un.t-,

His geology, acknowledged by the highest authority in this ag^. 
of scientific improrcment to he thus accurate, dn^adl(;s down in, 
his hands to be a merely inddenlal appendage to^ ^ enunciatioi^ 
of, the most rational and sublime theology. This l^t^. he ^id.

tlceof SacritiHDgtheBanieatihDal, for we find a hafer ainong the 
sactiffces of Abraham (Gen. xv.' 9-) The proofs of the existence 
of Fetishism io Bgypt in the time of Moses, and. that the 
Ejgyptians knew not the God of the Hebrews, arc complete. 
fa Exodus viii. 26., we find Moses saying to Pbaraoh, " shall 
ve sacrifice the abomination of the Egyptians before their eyes, 
and will they not stone us ?" In Exodus xii. \9, we find the beasts 
called the gods of Egypt; and in Exodus xxxii., we find 
Abron, in consistency with the idolatry which be bad witnessed 
ib Egypt, making a golden calf, and saying to the Hebrews, this 
iis thy God. Also, when Moses first presents himself before 
Pharaoh jo' Exodus v., we find the latter denying all know- 
ledge of the God of the Hebrews. 

Shall we, then, conjecture that Moses borrowed theology from 
the Hebrews on the one hand, and geological science frbm tlie 
E^ptians on the other, to compound out of them tTiat brief but 
uBique and perfect system ofboth, which is presented to us in the 
1st chapter of Geneus; or, is it possible that we could adopt 
tiny conjecture more absurd, and this, too, in utter destitution of 
all -proai that the Egyptians possessed any knowledge of geology 
in the tense in'which we use the term ? 

'' The result of our inquiry is, that the geology of Moses baa 
cbme down to us out of a' period of remote antiquity before the 
light of human science arose; for, to suppose that it was bw- 
rowed from, or possessed by, any other people than the remdrk- 
able raccf to which Moses'htmself belonged, involves us on all 
bands in the most inextricable difficulties and palpable absurdi- 
ties*. Of' that race, it has been long since justly remarked,

for th« words translated " Let the earih bringjbr^ "" are (ta- 
deshe hsaretz), which, in accordance with the obvious sense in 
Joel, would be better rendered " Let the earth shoot out."" . Froia 
this meaning of the verb, then, the noun would signify the 
tprii^ing or shooting plant, and as used here in contradistinc- 
tion to both herbs and trees bearing seeds, it is surely not recomr 
mjending any forced interpretation to suggest that it is meant to 
express that class of vegetables, which all botanists recognise aa 
being naturally distinguished by the obscurity af their means of 
reproducbon. 

It tends to support this interpretation, that the Hebrew ha^ 
a different term for grass, the common food of cattle (chatzir), 
which the lexicographers have shewn is derived from its tubular 
structure. Thus, in Job xl. 15, we have " he eateth ^rtuf 
(chatzir) as an ox;" and, Psalm civ. 14, " He CBXix\hgrai$ 
^chat^r) to grow for the catde," 

In several passages besides this of Genesis, we find deslK 
oontradistinguished from both oeseb and chaisnr, as in Deutero- 
nomy XXX. S. " As the small rain upon the tender lierb (deshe), 
and as the showers upon the grass (oeseb) i" and Psalm xxxvii. 
2, " They shall soon be cut down hke the grass (chatzir), and 
wither hke the green herbe (deshe) ;" and Sd Kings xix. S6, 
" They were as the herb (oeseb) of the field, as the green herb 
(deshe), as the grass (chatzir) on the house tops." These quor 
tations shew the want of uniformity with which the EngUslf 
translators have raidered these terms, and go to support ihe 
sense we would assign, to deshe.. 

But we must not conceal that there are thi:ee,, passages, iq 
which this word occurs, that might seem to imply, untiP closely 
examined, that we should not be warranted to restrict the sense 
of it in the manner proposed. One is in the 23d Psalm, " .Tb^ 
LmxI is my shepherd, I ^all not want He maketh me to lie 
down in the pastures of tender grass " (deshe)." On this we 
have to observe, thirt the word rendered here in the pastures^ 
has been rendered by the Vulgate, in various places where if, oct 
curs, and by the Septua^nt in some instances, desirable of beavr: 
tgfiilplaceSf and their accuracy in dcnng this seepis confirmed, by 

. the (drcumstance, that the Hebrew has another term for ,p^ 
« TlwiiMq|^nal.lnui^tion,'wU(iiii ABlttenLiM-,'-" l- , 



agree with Modem Geology t 67 

fare ; and. if tbts interpretation of that vord be admitted, then 
deshe might signify here plants ratlier fitted for lying down on, 
ia the moases and ferns, than for pasture, which would make 
out a consistent image expreesed in this clause or sentence, in 
opposition to the one derived from tlie abundance of pasture, 
which is evidently already sufficiently completed in the terms, 
" The Lord is my shepherd, I shall not want." This passage, 
then, when rightly understood, rather serves to confirm the 
meaning which we have suggested for desks. Another passage 
is Job vi. 5, " Both the wild ass bray when he hath grass 
(deshe), or loweth the ox over his fodder F" but no stress can be 
laid upon this, when we consider that both the ass and the 
horse eat, of choice, various species of ferns and equiseta, a fact 
which it is not unreasonable to suppose might be known to the 
author of a book which contains so mudi accurate and interest- 
ing natural history as this of Job. The plants, whatever they 
might be, which formed a supply for the wild ass, are at least 
obviously set in contradistinction to those which formed the fod- 
der of the ox. The third passage is Jeremiah 1. 11, " because ye 
are grown fat as the heifer at grass (deshe).'" But there is In a 
great number of manuscripts a various reading for eUahe here, 
by which the meaning becomes, " ye are grown fat, like a hei- 
fer thrashing, or treading, out the corn ;" and several circnm- 
stances shew the latter reading to be the more probably correct 
one. ^ 

It remains, then, very highly probable, upon the whole, that 
deshe., in the llth and ISth verses, is intended to express the 
cryptogamous vegetation. 

In our observations on the terms employed in the history of 
the creation of the animals, we shall arrive at some important 
conclusions that are more absolutely certain. 

The first thing that we would observe in regard to this, is, 
that there are two distinct Words, of very different origin, which 
the Enghsh translators have rendered, promiscuously, creeping 
creaivret or ^ivga, and also moving creatures, following, no 
doubt, the authority of the Septuagint, which baa given i^mr* 
fer'lKtth; thus occasioning a great confusioa instead of a clear 
and perfidious order of creations exhibited in the Hebrew

68 'Does ihe Mosaic Coimogony 

text The Grst of these worcia isshxretx, as io v&rm ftOtfa,'^- 
the history of the fifth day's work, " God said, Let the waters 
bring forth ahundantly the moving creature (sheretz),'' in the 
margin the creeping aeature.' This word is from a verb, which 
dgnifies to bring firik or to htcrease, or to mvUipl^ abandmtt- 
^, being the very verb which is rendered bring Jbtih abtmSant- 
h/ in the 20th verse, " Let the waters bring forth abundantly,'"' 
(is heretzu hamaim). We find the vet-b obviously having this 
meaning in other passages, of which we shall quote examples : 
Gen. viii. 17, " 7%U they mm/ breed tAundatithf (vesharetEu) 
in the earth, and be fruitful and multiply in the earth ;^ Exod. 
i. 7, " And the children of Israel were fruitful, ortrf increased 
abatidanlly (vaisberelzu), and multipried, and waxed exceeding 
mighty, and the land was filled with them;" ]£xod. viii. 3, 
" And the river ghaU bring forth fr(^ abundanth/ (vesharata), 
* " * and the frogs shall come up both on thee and on thy 
people, and upon all thy servants.'* 

From all this it appears that the proper translation of the 
noun sberetz is not the creeping, but the rapidlt/ multiplying 
creature. The creatures expressed by this nouD w£re part of 
those which were created during the fifth epoch. 

The other word translated creeping thing is (remes), and the 
creatures expressed by the noun were created during the HXth 
epoch. We shall afterwards shew that it hds a very'difierent 
meaning from sheretz. 

In the history of the fifth day's work the translators have 
rendered the Hebrew word (oph), by fowl. This limits its mean- 
ing so as to include only the birds. But the term includes also 
the winged insects, as is evident from Leviticus xi. 90, " All 
jifwls (haoph) that creep, going upon four." — rXhe proper trans- 
lation of the term is nol Jbwl hat Jlyifng thing, including die 
tribes of all kinds that can raise themselves up into the air ; as 
is indeed rendered obviously by the expression in the Bl'st verse 
of the'lst chapter of Genesis itself (cal oph canaph), "every 
fiying thing that hath wings."

UiatvthtktMfislation is erroneous. . In fact* nndvr U)e Greek 
DOT the English translators have been con^steiit with them- 

' selves in translating the Hebrew wonJ (ttian) or (thanin), for it 
occurs in both these forms. We ^nd them in other places 
translating it severally by the terms ^mumj, and dragon. It 

. would , he tedious .to quote the passages where they have thus 

. varied, from themselves. We shall refer to Ezekiel xxix. 3, for 
the latter sense, " I am against thee, Pharaoh, King of Egypt, 
the greai dragon (hathanim hagadol) that lieth in the midst of 
his rivers,^ where the Septuogint has n> }fiuun» m fuyat. The 
figure in this passage is evidently borrowed from the crocodile 

' of the. Nile, and tl)is circumstance of itself would shew that 
dragon, in plaee of whale, would be a better translation in 
GeneMs. But (thanin) has a still mpre comprehensive meaning. 
We find two words formed from it, one of which (Leviathan) 
is the specific name of the crocodile, as is obvious from descrip- 
tions of Job chap. xli. and of Isaiah chap, xxvii. 1, in which 
last passage (thanin) is also used, — and the other (Fethan) is 

. the specific name of some serpent, as is obvious from the refe- 

.rence.to its poison, in Job xx. J4, and Deuteronomy xxxii. 33. 
In this last passage we also find poison ascribed to the thanin ; 
" Their wine is the poison of dragons (thaninim), and the cruel 
vraom of asps (pethanim) ;" so that here it is evidently meant 
to express a serpeit, as in Ezekiel and Isaiah, as we have seeti 
above, it signifies one of the lacertine species. 

These references, which we could have greatly extended, 
were it necessary, are sufficient to prove that (than) or (thanin) 

, was a sort of generic, pr rather clasacal, name, to designate the 
serpent and lizard tribes ; and that instead of great whales in 
the, 21 St verse, the translators should have given the words 
great reptiles*. 

, . The result of pur criticisili is, that the work of the fifth epoch, 
as described in Genesis, was the creatiun of the inhabitants of 
the waters; of the birds, winged insecl^, and reptiles ; in fact, 

;0f the oviparous races named in detail,^ with some omissiops,

idiich are to be Accounted for by the uniformly ocmdeBBed aad 

brief form of the whole narration. 

We proceed to the wotk <^ the sixth epoch, whidi concluded 
vith the creation of man. 

In the Engli^ trandation we find crteping tkmgg again in- 
cluded among the b^ngs vhich were created during tliis period, 
and these Engli^ terms, in their most commonly received ac- 
ceptation, imply some of the insect or reptile tribes. We hate 
seen that the Sepluagint countenances the interpretation creep- 
ing things; but the Hebrew term (remes) does not. Thiais 
derived firom a verb which signifies to move, and which is to 
far from being limited in its application to the insects or the 
reptiles, that, in Psalm av. 30, SEl, we find it appbed to tbe 
beasts of the forest and the young lions: " Thou makest dark- 
ness and it is liight, wherein all the beasts of the forest do creep 
(tiremos). The young lions roar ofler their prey.^ In the 
24th and Sfith verses, (remes) is grouped with cattle (behemach), 
and beast of the earth (baith haaretz). Proofs are abundant, 
and too tedious to be all referred to, that by (behem^) the 
Hebrews generally expressed the larger herbivorous animals, 
and by (hdth haaretz) the larger beasts of pi^y. (Pot the tot- 
mer see Genesis xxxiv. S3, and for the latter Leviticus xxvi. 22). 
Thus we find races of mammalia expressed by these terms, and 
to comprehend the whole class we must understand (remes) as 
referring to its other tribes. It is at least no race of insects 
that can be meant by the term, for, in point of fact, where any 

'of these are obviously meant in other Hebrew passages, either 
the name (sheretz) is given to them as in Leviticus xi. 42, 

" " Whatsoever doth multiply feet among all cret^>ing things,^ 
(hasheretz), or the name (oph), as we have already seen. 

It. is true that remes is applied to the oviparous tribes, bi^t 
not as a noun or name, but as a verb to expren their motion, 

ijust as in some passages above quoted, we have seen sberetz ap< 

'plied as a verb, but not a name to mammalia. ' . 

Previously to setting down the following table of cmnddencw 

.between the Ist chapter of Genesis and the results of gedogical 

observation, it is necessary to make a remark on me passage in 
Humboldt's t^e of geological formations, which possesses a 

claaucal celetHity over Europe. Id that table, folbwing an 



agf-ee with Modem Geology f 71 

earliw authority, be has placed tbe fonoatioos of Iraasition, in 
the iimestonea of which are found several epectes of shells, inter- 
mediately between the primitive formalions and those contadning 
bitumiDous coal \ and his table would thus indicate that an anU 
.mal creation had preceded any v^etable one. We shall not 
need to discuss the quesUon, wb^er the formations named 
Transition are conridered in a right point of view, when they 
are placed between the primitive and pit-coal strata, since it is 
sufficient for our present purpose to remark, that several oBser- 
vations, among which we may particularly refer to those of 
Thomas Weaver, Esq, F. R. S. on the gecdo^cal relations of 
;the south of Ireland, have proved that the anthracite or glaac«- 
coal.of tb^ tranution, fqnpations, wiih some of its accompanyif^ 
strata, are full of impre^ons of. various plants; lo that in tJie 
transition strata a vegetable creation is discovered as well as an 
animal. 

In the following table we have taken the geolf^^al facts 
from various authorities. The passages quoted are selected 
chieBy on account of their brevity. In the quotation from and 
reference to Genesis, the events on which geology can throw no 
certain light are in italics.

Id the above Table, we have not taken, advantoge of tJie di*. 
iinction which, we conceive, we have gone far to prove, is ex- 
'pressed in the Hebrew text between the cryptogamous and the 
Other classes of plants, but have set down the whole vegetable 
kingdom as forming only one element in the table. We shaH 
also allow tbin the 4th, 5th, and 6th Nas. may be hable to be 
interchanged among themselves, in respect of place, and shall 
hinge no .argument upon thetn, farther than what arises froia 
the drcumstance that they are all placed in one group. Yet, 
after these abatements from the number of particulars, the 
coincidences here shewn between the order of the epochs of 
creation assigned in Genesis, and that discovered by get^ogy, 
are calculated to excite the deepest attention. Human science, 
in the probahihty of chances, as illustrated by La Place, has put 
us in possession of an instrument for estimating their value ; aqd 
we feellamply entitled to take advantage of it for Uiat purpose, 
for no case could well be pointed out, where it would be more 
correctly applicable than in this, where the coincidettces assume 
a definitely successive numerical form. We are entitled to 
adopt even the very language of Laplace, and to say, ** By 
subjecting the proliabitity of these coincidences to computation, 
U !s found that there is more than sixty thousand to one against 
the hypothesis that they are the effect of chance *." 

It is thus, then, that the discoveries of geology, when more 
matured, instead of throwing suspicton on the truths of revela. 
tion, as the first steps in them led some persons to mfuntain, 
have furnished the most overpowering evidence in behalf of 
one branch of these truths. The result of these discoveries hae 
been in this re^)ect similar to those of the Chinese and Egypi- 
itian histories, and the Indian astronomy, but much more strik- 
;ing. Eminant men liad fJedged their fame in setting, up tjl^esfi 
iHSstories, and that astronomy,' in' opposition to "the chronology 
iof Geneas ; but fuMher- and more careful inquiry into their 
'true characters, discovered that, when rightly understood, they 
'only tend to confirm it.

** that the order which the coamc^ny of Moses asiig^s to tb*

been guilty of no improper mixing up of divine and humaa 
things. We have examined the meaning of the tertos in the 
first chapter o{ Genesis, in consistency with the acknowledged 
rules of criticism, and only by the light contained within itself 
tar that thrown upon it by the other bookst in the hdm slan- 
guage with which it is associated. The human science we hnet 
not extracted from any part of the Holy Scriptures ; we have 
taken it simply as we find it in the works of emii>ent geologists 
As the latter is not a philosophia pbantastica, but a deeply in- 
teresung science, constructed by that method of careful i^)ser- 
vation and cautious induction, which Bacon was himself the first 
to recommend ; so neither can the sense of the Scriptures present 
to us a religio hieretica. If our science, thus construeted, mi 
■ our religion speak eo obviously the same language, as we have 
seen they do on one important point, what else, is the strictest 
application of Bacon's philosophy, can we deduce from the cii> 
cumstance, but that both are certainly true ? 

It does not come under our present subject to discuss the his- 
torical and moral evidences of the divine revelation of the Scrip- 
tures ; but both are so full, even to overflowing, and impise

fit to protect them from the cold of the northern regions, would

has been no change of temperature since the creation of animals.

VIBANVS, M. D. &C. 

The doctrine of organization is founded on comparative anato- 
my, or the systematic distribution of living bodies, and on or- 
jisnic chemistry. It is not to be expected that we are to give 
here any thing but a mere outline of these sciences ; a few land- 
marks, which I think have some pretensions to novelty, and are 
^nocc correct then those which have been hitherto most general- 
ly tidmitted. 

We can arrive at no mutual und,erstanding in biology until 
acuirate definitions ,aie given of the classes, families, genera, 
spd species of living bnngs. Ever since natural history has

'been aoniethmg more tlian a, mere crude digest lof MBCOBOeoted 
facts and observations, philosophers have oonstantly endeavout^ 
ed aflerthe discovery of an airai^eiocBt in which. theofajecU 
of their inquiries should belinlced after tkeir natural -afEnities ; 
while, at the same time, the characters of its subdivisicHia sbculd 
possess the utmost simplicity, by being derived fnwi a sin^e 
BjEtetn of organs. It may, in & maniiM'i be compared with itfae 
'philoBopber^s stone, whether be ma«ly resort to 99ch aa bm~ 
rangeraent for the purpose uf discovering the name of an un- 
known animal or plant, or whether, with hi^er views, his r». 
searches enter deep into the pliilosophy of nature. With the 
first object onlyin view, external chantotersslon^niay si^ce,aQd 
ihe more easy these are of detection, the bett» arathey.fitttd 
for their purpose. The ^nd of natural atSnitics is quite fub- 
ctfdinate to this primary object. But if his object be of tlie 
other description, the characters may lie deep, and be of the ut- 
most difficulty to discover. His arrangement will be the more 
perfect the mure completely it expresses the sum of all the ex- 
ternal and internal structural diffovnces, and the more uniform 
the parts are from which the characters are taken. 

Of late years systems have been constructed upcm the last 
of these principles. But their bases have been always such 
as I cannot admit. One of these is the principle, That all 
higher fttfmationn include those lower in the scale ; the most 
perfect organs in the former having already existed in the latter, 
but in their undeveloped state -, that there is one universal type, 
only modified in the degree of its development. There is muob, 
bolhoT truth and of error, in all this. It is true that every or- 
ganised being advances from the umpkr to the more conipoijQ^ 
. ia its progressive growth, and that the early stages of the life of 
an animal high in the scale present many points of similarity with 
the perfect state of another lower in the series. But these r&. 
semUances hold merely in .external relations, and the .numerous 
points of dilTerence can by no means he overlooked. 

The foetus of the inammaliaand of Wrds is an 'aquatic adion^l, 
which respires not by means of lungs, aiid as such bas a simpTe 
circulation like a fish. But in all other respect^ its x;ire«l.ating 
system is constructed upon a totdly different princ^e' ftom.a 
fish. The apparent anaTogy vanishes upon a close* inspection.

necessitates a proportiooate iocreaK in the rwiety and perfectidD 
f^ the several orgaD& The intellectual faculty is more perfiKt 
in man than in any other terrestrial eiistenoe. He, therefere^ 
merely in an organic point of view, stands at the head of the 
scale of animals. . But this does not oblige us to suppose tlwi 
in him every organ has reached the maximum of its devel<^ 
ment. An important line of distincbcMi must here be drawn 
between the organic sphere of the senntive and of the amply 
organic life. With respect to the former class of u-gans nun 
is decidedly at the head of- all animals, but by no means in tO' 
^lect to the latter. His alimentaiy appn-atus, for instance, It 
not nearly so complicated as in many other animals. - Betweot 
him and the lowest existences there are many members, of whioh 
one cannot be said to occupy a higher place than another. One 
being is best adapted for one purpose, and another for a diSa* 
rent purpose. They can only be placed in a linear series, by 
arranging them according to the type of some one oi their or- 
gans. 

3. An original form may be very easily supposed, out of which 
all living things are developed. This development is not in one 
but in several directicms. Each of these principal directions 
again give nse to new subdivi^oas, so that the whole assumes 
somewhat of an arborescent form. Difierent twigs, however, of 
one of the branches i^len unite those of another higher or low- 
er in llie scale. In the midst of all these diversities, a general 
similarity persists between the various organisns and' tbmi se- 
veral parts, whiqh enables us to trace them up to a common 
fundamental, fbmi. No cooelu^enh- lioweyef, can be ditami 
from the nqiilarity of two ft^ms regarding their respective 
superiority or inferiority in point of development. Suoh simi- 
larity may result from the lateral concurrence of two forms de-i 
rived from totally dijferent twigs. Insects, for example, resem- 
ble the vertebrata in some of their organs, but are otherwise so 
diffenent from them in all ihar parts, that this partial exc^ptjoa 
cannot be considered to result from a higb^ development of 
the form peculiar to insects. As in the higher animsls, ao wft 
can likewise disUn^ish in tbe aUmentary ciod.t£.iiaeota,»,^

paration into ceeophagus, straiiRcli and intestiiie. The latter, 
iiuM«over, is not as in the former attached to a liver. Its poft- 
ttrior extreimty certainly opens as in them above the generative 
cu^sBs. But their proper bHigue is not atuated bdow but 
above the entrance of the pharynx. When, however, we apeak 
^ development (rom a common primitive form, and the combi- 
BBtion of one form with another, it is not to be understood that 
these developments and combinations follow the same rules as 
pairing and generation in the presently existing nature. 

a. Noconduaon can be drawn from the absence of an or- 
gan, regarding its pm^se, nor vice versa. An example of 
dris is furnished by the auditory ossicula of 6sh, discovered by 
Weber, which are evidently parts of the vertebral column, aU 
Plough attached to the organ of bearing, which in other ani- 
mals is quite unconnected with the column. Another instance 
is in the mandibules of the Crustacea and insects. These organs 
have the same function as the maxillK of the vertebrata. But 
they do not like the latter move in a pkne parallel to the axis 
of the body, but in one at right angles to this axis. In many 
Crustacea, moreover, they perform the function of legs. Oa 
the contrary, the organs of these two classes which move in a 
plane umilar to that of the jaws of the higher animals, viz. the 
upper and under lips, have a totally different funcdon. 

To return to our proper subject, the distribution of living ex- 
istences ; according to our principle of considering life and the 
intellectual faculties as one and the same, we may be allowed to 
consider the organs through the medium of which the activity 
of the living printnpie passes ta the other bodies in the animal 
kihgdoiii, as those with whose perfection ' the. sbntcturs pf dM 
othw parts must stand in oonnection. Atid the aiaM'~inilmaie 
the connection the higher the gradatjim of life. These organs 
are the brain, spinal cord, and nerves. 

The presence or absence of these organs, as chareeteris'mg 
the existence or non-existence of voluntary motion, has always 
been conndered as the basis of the two grand divisions of living 
nature into animals and plants. No nerves, it is true, can bft 
detected in' the simpler animals ; but a» they have been di|«»: 
vered in some to which they were formerly refbsed, and a^ thes^

^tribute of all aniDials, even the lowest. It ia quite otherwiae 
vith plants. Their tissues are so transparent, that if a nervous 
matter at all analogous to that of the nervoua animals existed, it 
would long ago have been observed. 

Here is, therefore, a negative character of [^ants ; and in 
their classification some other system than the nervous must be 
made the basis of division. Their positive character consists in 
the compo^tioo of their whole internal substance of solid cells 
and uobranched vessels. Their celts are separated bj intcrvBla, 
and are connected together in a. reticulated form. These inteV> 
vtds' have no proper coats. Globules and not cells are the ele- 
mentary parts of the animal tissues, and their vessels are rf- 
ways branched. When we approach the confines of the animal 
and vegetable kingdoms, — whenever the vegetable tissues are 
destitute of solid cells and of vessels, it is always difficult to de- 
termine to which of the two kingdoms they ought to be referred, 
from their want of the distinctive characters of the imimal and 
vegetable tissues. 

It might be supposed that the embryo, with its envelopes, 
was the miniature enpression,— the microcosm of the perfectly 
developed animal, and that the complexity of each were directly 
proportioned to each other, so that tlie degree of alfinity between 
organic existences might be concluded from the similarity of their . 
ova and embryos. The appreciation of these resemUJances has 
great or even insurmountable difficulties in animals, but is much 
easier in plants. The characters deduced from the formation 
of the embryo and its envelopes, have Iteen found the fittest for 
the natural arrangement of plants. They are the bases of the 
JuBsieuan System, which I must suppose to be well known to all. 

Rudolplii wa^ the first who attempted to arrange animals aci- 
cordlng to the structure of their nervous system*. He divided 
them into those with, and those without, a visible nervous sys- 
tem ; but such a division is of no value for tacAogy. Our au- 
thor has only given the most general distinctions of the classes 
provided with a nervous system. I have ajso occupied myself 
.mut:h with this Ruhject ; but my contributions are still merely 
fragments; but I doubt not that avery splendid superstructure

might be raned, if the principles were af^ied to the fiUJBg up 
of all the gapB- 

' AccordiDg to mj view, there are two great divinoos of the 
■aimal kingdom. The one connsts of thoce provided with a 
true spinal cord, inclosed within a shut vertebral column, which 
is always wanting in the other. In the fcHmer, the whole brain 
k situated above the pharynx, and inclosed in an osseous capsule, 
the skull. In the other there is either a single cerebriform mass, 
or several nervous knots united tc^ether by cords of nervoua 
substance Enirrounding. the cesophagus. The mass analogoua 
to the brun is eomeUmes above, sometimes below this canal, 
and is developed in an osseous or homy captule, whidi separtfes 
it from the other parts of the head ; and its posterior part ^ves 
«nt DO proloogaUon ctMnparable with the spinal cord of the other 
animals. This dividoD, therefore, coincides with that of La- 
marck into Pertebrota and Avertebrata. They might also be 
called Cnmta2 and ^crontoZanimalsL We shall, however, adhere 
to the old epithets of Lamarck, to avcud overloading biology hy 
the introduction of new names. 

In all the vertebrata, the anterior extremity of the sfunal cord 
inctosed in Uie cranium, possesses the same form that it does in 
nan, and in ^ undergoes a consderable augmentation both in 
toass and volume, compared with the rest of the cord. Even 
from the numerical differences aiE this {Hxjportion, four classes 
can be distinguished in these animals. I found the limits of the 
proportional weights of the spinal cord to the brain to be, —

83 Dr Treviranus on the 

The first class- cotnprehendB the mammalia, including man ; the 

second, birds; the third, reptiles ; the fourth, fish. 

The following are the most impc^ant of the other neurolo^ 
cal difierences of these classes : 

In the mamrnalia, the portions from which the (^factory and 
optic nerves take their origin, coalesce with the rest of the cere- 
brum, no limits being distinguishable between them. In all the 
other Tertebrata, the cerebrum is distinguished into anterior and 
posterior hemispheres, from the former of which arise the olfae- 
toiy, and from the latter the optic nerves. The posterior bemift- 
pheres may be either separate or united together in the me^al 
line. They are separate in birds, united io reptiles and fi^es. 
Moreover, these posterior hemispheres may be smaller or larger 
than the anterior, — smaller in birds, reptiles, raya, and sharks; 
larger in other fishes. 

' The mammalia possess a cerebellum, cousisting of a middte 
portion (the vermiform process) and two hemispheres, imd its 
vertical section displays an arborescent prolongation of the Oord 
(arbor vitse). In birds the hemispheres of the cerebellum are 
merely rudimentary ; the vermiform process, however, still con- 
tains a distinct arbor vitee. This hist is entirely wanting in rep- 
tiles and fishes, and the cerebellum consists of a simple sack, 
formed by a thin layer of the cord. 

The mammalia alone possess the pons varolii (or great cere- 
bral ganglion). 

In fishes, there are found at the base of the brain, behind the 
optic tracts, two symmetrical eminences, of such extent that they 
form the greater part of the basoj and do not much yield in faze 
to the posterior hemispheres. 

The avertebrata, in the same way, fall under two great divi- 
sions, according to differences in the structure of their nervous 
system. In the one, there is extended along the abdomen, in 
two rows, or in the mesial line, a series of ganglia united to one 
another, and to the middle of the under half of the cerebriform 
ring by nn^ous filaments, and the upper part of the ring con- 
sists of two hemispheres, immediately united together. In the 
other division, there is no series trf ganglia extending in regular 
order the whole length of the animal, and the two lateral tube- 
rosities of the ring are not immediately united, but by means of 

.o;.|c

bands chE pervoas BUbdapc^. To tbe first division belgog tbo«e 
animals whose bodies crni^t of articulated rings, compriuDg the, 
cru^acea,insects,and wc»iBs; to the second, the molluscous ani- 
Boals and zoophytes. 

The distinguishing neurological mark between the Crustacea 
and insects, and the wonns, is th^ inequality in the several pqr- 
tions of the abdominal ganglia. This is obyious in the higher 
insects at the first glance. Their thoracic ganglia always di^r- 
in form and size from the abdominal. The differeni^ is not, so, 
marked i& the genera nearest to the worms, — the MiUipes, St^ 
iope^drum, and JuliiS. But even here the ganglia, from which 
arise the nerves supplying the organs of generation, are differ- 
en( in size frcan the others ; whereas in the worms, no other 
distinctiira is observably between the ganglia than a general de- 
crease in size and relative distance towards the posterior end of 
the animal. They have, in common with most cruatacea and 
insects, the possesion of but one series of ganglia situated in the 
middle line of the abdomen, and composed of a symmetrical 
right and left half. A deviation ^m this structure exists in 
the phalangiffi which possess ganglia on both sides of the abdo- 
men, but united with one another only by simple filaments. 

This first division passes into the second by the cirrhipedes, 
which, in the articulated posterior part of their bodies, possess a 
series of ganglia, as in the former animals, but in the upper por- 
tion of their cerebral ring, no hemispheres immediately connected 
together. Among the mollusca, there are families distinguished 
from all other animals by the want of symmetry of their brain. 
In those where the cerebral ring is symmetric, it has no central 
mass. Nothing certun is known of the nervous system of the 
zoophytes. But from the general radiated structure of this class 
of animals, it is probable that it is merely a simple cord, sur- 
rounding the orifice of the alimentary canal, or an aggregate of 
gangha united in the form of a ring, and which give off nerves 
in a radiated manner. 

Much is still wanting to carry out this neurological classifica- 
tion in all its details ; and even did we possess an adequate mass 
of observations, a more uniform division could hardly be pro- 
posed. ]t will, however, be by no means out of place to trace 
the concordance of the characters deduced from the nervous

system, with the natural characters of the faimlies fw tbe clan 
of maminalia. 

The proportion of the spiaal cord to tbe encejrfialon wliich 
we have already found of such value in the primary divisions of 
tbe vertebrata, is no less impwtant in their further subdivtEdoD., 
I have found ittocorrespond with, and to follow, anak^ous gra-- 
daUons, with the natural characters io the genera and species. 
Of these dimensions, themost important are the greatest breadths, 
of the two organs, which agrees with thar relative weights, and 
very nearly with the transverse diameters, of the cranial cavities, 
and of the occn|ntal foramen. In the fcJlowing table, I have 
brought together several of these relations, and have ranged the 
^)ecies according to thdr natural affinities. Those marked with 
an asterisk are taken iircHn TiedemamCt Iconet. Cerebri Simia- 
rum et quorundam Mammediwn Rariortim ; ihe others are 
from my own observation. Most of these last depend ou im- 
mediate measurements of the brain and cord. Those marked 
with a cross, are tbe relative breadths of the occipital foramen 
and of the cranial cavity. 

The greatest breadth of the spinal cord immediately behind 
the pons is to the greatest breadth of the cerebrum,

We have heie a double Bsnea, eia iocreaaiiig and a decreaung. 
The first ranges &om man to the VirgiDian Opasaum ; the 'second 
continues from the Opossum to the Cetacea. The intermediate 
monbers of the Srst series are, first, the apes, then the makis 
^Lemur), then the plantigrade or digidgrade carnivora, and, 
lastly, the insectivorous genera of Erinaceus, Talpa, and Ve&> 
pertilio. In the second series, the links are filled up by the Ho- 
dentia, <^ which the hare fmns the passage to the Ruminantia ; 
to vhicb follows the Fachydermata, which pass through the 
1%'oCK'intai the Cetacea. Thus the rdations of the spinal cord 
to thb brain in these animals, entirely coincide with th^r other 
ndtiirkl affinities. Sonie writers, it is tttie, have regarded th»r 
affinities diflferently, making the bat succeed to the makis, and 
the phoca to the plantigrades. But, in the determination c^ 
these oFBnitiee, we must not be swayed by a few of the more 
obvious external marks, but by the whole internal as well as ex- 
ternal conformation. Upon such a basis these animals will as- 
sume the order that we have ^veu them above. The only ana^ 
l<^y of the bets wiUi the makis is in the pectoral mnimnjn ; and 
the phocic ere intimately unconnected with the cetacea throu^ 
the geuus Maoatus. 

By this, however, I am far from assarting the mammalia can 
be ranged in an uninterrujKed series, according to the propor- 
tions of the brain to the c(»d. Even in the above list, deviations 
are found from such an order. This is owing partly to the re- 
lative breadths of these two organs not being exactly indicative 
of their relaUve masses ; and to the circumstance of the number 
of individuals in which die masses are determined with precision 
b^g still too small tn justify the formation of an exact series. 
Only, if these defects were supplied, it might be expected that, 
in cn-der to preserve the scale of natural affinities, the vacuities 
of the ascending and descending series should be filled up. It 
cannot be doubted, for example, that, in the sloths (bradypus), 
the brain, compared with the cord, is smaller than in the makis 
and (he uppermost of the carnivora. They are, however, im- 
metfiately conuected with the makis, and must be placed in the 
series between the lemur and ursus. Ifthe proportional breadths 
of (he organs were as 100 to 300, the descending scries from 
man to the opossum would chanee into two others, one from man

to the sktdi, the other froin the besr to the opossum. Faiilier 
mquuies would likeilrue disclose otherintenaetUate series. Sudi 
iMemiptions of the principal seties are, however, quite corres> 
pondent to the laws of natural afiinitj. They would only 
transgress these if interposed members gave rise to recuireDt 
«eries in one of the two principal ; if, for instance, an animal 
which, according to its natural affinities, succeeds to the sloth, 
should, from the proportion of its brain and spinal cord, stand 
^wve it. But I do not believe that such a genus can be found. 
As every genus and spedes, not only of the manunalio, bat 
also of the other vertebrated animals, hsa a certain proportion 
between its brmn and spinal cord, in the same manner each part 
of the brain, especially the cerebdium, bears a definite propor- 
tion to the other parts. Hence we might deduce fuither spedh 
"Rc BaA generic marks; and one day we may be able to distin- 
guish the whole of the vertebrata by the numerical masses and 
^mensions of the parts of the encephalon, and range them from 
this character according to their natural afSniti^. The relation, 
it is true, varies in diSerent individuali; of eacli qiedes, biit there

The specimen analyzed was found near Can^u^ io a, por- 
.phyritic greenstone. It was in the form of long narrow crys- 
tals, nearly transparent and colourless, of a foliated structure, 
and vitreous lustre. Its specific gravity was 3,(i$9. The larger 
(arystals frequently present a flat conchoidal fracture, which first

induced me to suspect that it was not f^l^iar. From the great 
AfficuUy that I experienced in procuring the mineral in a puie 
state, the analysis was made upon a small scale ; hut it was re- 
peated with nearly the same result. It appears, then, that this 
mineral is labradorite, with the best analysifi of which the fore- 
going nearly n^r^es. The large crystals of labradorite that are 
imbedded in trap-rocks are very much cracked, and so impure 
(hat they cannot be employed for analysis. 

About two miles to the west of the village cS Milngavie, near 
^e road between Glasgow and Strathhiane, there is a.very re- 
markohle brown porphyiitic trap, that contains large, and beau- 
tiful -crystals of yellow labradorite. These crystals are ^racked, 
-and when heated, present numerous brown spots, which show 
that they are not pure. The following is their compoution :-~

All the analyses of Ubradoiite that have hitiierto been made 
differ a little &om each other ; some agree with my first analysis, 
while one of Ehtproth's differs but little from the last. It is 
probable, that, owing to its structure, labradorite has seldom 
been examined in a pure state. 

The cjiemical dtaracters of h^radorite enable us to distia- 
guish it from ielspar, even when the quanUty for examination 
does not exceed a grain. For this purpose the mineral, in the 
state of an impalpable powder, is treated with weak muriatic 
atnd in a watcb glass, and gently heated for an hour. The so- 
lution is then evaporated to dryness, and the saline re»due is 
heated until the excess of acid be expelled when it is redissidved 
in water. To the clear solution, when warm, a . few drops of 
- oxalate of ammc»iia are added, which produces a precipiute of 
oxalate of lime if the mineral he labradorite, but does not pro- 
duce a predpitate if it be pure felspar. 
Dr Macculloch mentions, that the glassy felspar whicb he fouod 

I ,l,z<»i:,.,G00gIf

at Sky' frequeDtly reaeUibled lalnwloiite. I have se«i msny 
i^)eciniens from that idaod to vhtch the latter name must 
be applied. The miDerol, which givea a porpbyritic aspect to 
Bome oF the pitchstone of Arran, appears to be glassy felspar ; 
as far, at least, as I can judge, from having examined a very 
smfdl fragment of it. -The porphynndal Craps, on the western 
boundary of the Scotch coal distnct, more frequently owe their 
structure to the presence of lahradorite than to that of felspar. 
Thb last mineral, with its usual -characters, very rarely occurs 
in them. We frequently indeed find a white, opaque, fdiated 
mineral, destitute of lustre, which has generally been called 
felspar; but I have procured both lime and soda from this 
substance ; therefore it has, in some cases at least, been impro- 
perly named. The trap-rocks appear to conttun other minerals 
which resemble felspar in many of th^r characters, but differ from 
it in composition. One of these, which I found in the nei^bpur- 
bgod of Stirling, is of a red bright colour, opaque, foliated, and has 
a silky lustre ; from the small quantityofit which I could procure 
I could only determine, that it contmned a good deal of perox- 
ide of iron, and a little lime. The analysis of another was pub- 
lished some time ago by Dr Thomson, who called it Momite. 
It is very remarkable ^st the composition of mornite is precise- 
ly the same as that of the first specimen of Isbradorite that I 
examined, excepting that it does not contain ah alkali, but it . 
contains a quantity of protoxide of iron, exactly equivalent to 
the soda in lahradorite. The external characters of momite and 
lahradorite must also be very amilar, for the inineral dealer from 
whom Dr Thomson procured the former, when I showed him my 
specimens of the latter, immediately called them momite. I bate 
not seen this tnitieral, which was found in a trap-rock in the north 
bf Ireland. The granitmdal traps of ihe Scotch coal district, 
on the contrary, very freqilenOy present wdl characterised crys- 
tals of felspar, and rarely lahradorite. They often, however, 
contain a white mineral, which, through a great extent of rock, 
does not present any of the characters of fejapu, but rather re- 
sembles a zeolite ; and these difitr very much, in all their cha^ 
racters, from those which contain felspar. It wonld be easy to 
arrange the granitoids, from th«r external characters, into three

classes, and to give tbem very expressive names, if the miqerals 
which they contain were well known. The unicoloured crystAl- 
Une traps occaaon&Uy contain labradorite, and the presence of 
tbi$ tnineral may account for the soda that has generally been 
found in tbem, as well as in basalt, to which they are closdy al- 
lied ; but it does not, in some cases, acqgunt fw the wholv of the 
soda, so that they probably contwn other minerals, of which tbja 
alkah forms a constituent part. I have analyzed two of these 
rocks, that contained labradorite, and the analyus differed but 
little from those of some basalts. The neighbourhood of Glas- 
gow affords some very fine specimens of columnar trap, which 
all contain labradorite. The range of large and regular cdumns 
that stands on the ude of a wooded hill, a little to the south <^ 
Strathblan^ is well known. It is composed at a dark green trap 
or greenstone, contwning crystals of that mineral. The same 
may be said of the black basalt, that fonn^ the remarkable hori- 
zontal columns, near Ahmarry turn^nke, on the road from GIas> 
gow to Drymen ; and also of the columns that are found in more 
than one place on the Eilpatrick and Cathkin Hills. So that 
iabradorile is probably one of the minerals of which basalt is 
often composed. 

I have made these remarks upon the atuations in which I 
have found labradorite, because I believe that we cannot at- 
tempt to arrange the trap-rocks, or give them expressive names, 
until we are better acquainted with their composition. The pre- 
sent nomenclature of these rocks is very defective, and, not be- 
ing formed upon any fixed principle, it cannot be impro'^. 
The names must either be multiplied to such an extent as to 
render them very burdensome to the memory, or be applied so 
,)oosely, as always to require a. definition. The short <u>d simple 
terms now in use have not the flexibility which names, applied 
to pVgects that are constantly varying in thar characters, shoHid 
possess. It would be better to employ iu geology, as often as 
possible, compound descriptive names, that would indicate the 
structure and -compoution of rocks. Such names would, in many 
cases, be shorter than those now employed, as they never would 
require a definition ; and, when formed upon a fixed principle, 
they might be multiplied without loading the memory. As &r

as the trap-mcks are concenied, they can be accurately aamed 
in this manner only ; for we frequently find among them rod» 
of the sane conipositaon, but diffeiiog ia structure ; and, on the 
oontrary, th«r structure is often the same, when their compoei- 
Iton is diS£Tent. They are easily arranged in a few classes, by 
their external characters ; and the class to which the rock be- 
l(»gs may be expressed in a single word, while its compoaitioa 
may be denoted by two or three. There are some coses in 
which we should still be obliged to use arbitrary terms; but 
this should not induce un to reject the only painciple upon 
which an expressive and convenient nomenclature can be formed 
for the greater number of these rocks. I hare long been in the 
habit of using those compound terms in a district which presents 
trap under a great. variety of forms; and I should menUon the 
mode that I have adopTed, to render them as short and expres- 
^ve as posfflble, but that my observations and experiments on 
the subject are far from b«ng completed. 



Physiotogical Investigations arising Jram the Mecfianical 
Effects <^ Atmospherical Presgure on the Animal Frame. By 
JOHM Dalton, F. B. S. 

A- PBBIOD of a century and a half has elapsed since the inven- 
tions of the barometer and the ur-pump. In this time the weight 
of the atmosphere, its elasticity, its specific gravity, and many 
other properties, have been ascertained experimentaUy with aU 
most mathematical precision. The weight of the atmosphere, that 
quality we have more particularly to consider in the present 
essay, is not constantly the same, as is proved by the rising and 
fallingof the barometer. It varies in this part of the earth from 
^*|tb tOi';;thofthe whole weight at certain times; but those varia- 
iioDB are gradual, so that it requires some days or weeks before 
the w^gfat passes from oqe extreme to the other. On an average 
the weight or pressure of the atmosphere amounts to 14^ lb. on 
.eexii square inch of surface of the earth ; and, as fluids press 
.equally in all directions, every square inch of surface, whatever 
may be its position, must be subject to the same pressure. The 
surface of the human body, as well as that of animals in general, 

.o;.|c 



the AtmupherietU Prature on ^ Animal Frame. 91 
has to sustajn this pressure ; and it will be fennd by calcuktioo, 
that die whole surface of a middle-rized person, irill have to lup- 
port fhim 15 to SO tbos of pressure all acting inwards, and hav- 
ing no other mechanical tendency than that of squeezing or com- 
inressing the matenals of which the body is composed into a leaa- 



The above is a statement of &cts, alt of which I believe to be 
incontrovertible. But a very cfifficult question arises out of them, 
How is it that the animal frame is utterly insensble <^ the whole, 
«r of any part of this enormous pressure upon it ? In ordJoary- 
we feel no pressure on the surface of our bodies, either extenud 
Or internal ; neither when the barometer is Btationary nor whea 
it is in a most fluctuating state. I have never met with a Bat»- 
factOTy answer to this question, and I doubt whether such a mie 
has ever been given ; yet it must be allowed to be one of imports 
mce, both as it affects the phyaok^ of the animal and vegeta- 
ble kingdoms. Having had occa^n for a few weeks past to 
rumiaate on this subject, some new views have occurred to me ; 
and it is the oti^ect of the present essay to unfold them, in 
order to elucidate die phencHnena arinng from serial pressoieon 
the animal economy more especially. 

It is pretty well known that the specific gravity of living men 
in general, is less than that of water. Mr Robertson, frnmerly 
librarian to the Royal Soraety, procured an apparatus for the 
purpose of determimng the ^Mcific gravity of the human body. 
He chose ten men promiscuously for the purpose. Of these, 
three were found very nearly of the same weight as water, one 
being a little heavier, and the other two a little lighter than wa- 
ter; two others were found only about .8 the weight of .water; 
but the other five were of intermediate specific gravities. The 
average of the ten was, height 5 feet 6g inches; weight, 146 lbs. ; 
specific gravity, 891 ; bulk, 2.618 cubic feet. From this I think 
we may safely infer that the body of a full grown living man, 
when plunged over head in water, will be found upiH) the average 
to be nearly .9, the wright of an equal bulk of water. 

It is remarkable that all the component parts of the animal 
frame, at least of the human subject, are severally specificaUy 
heavier than the whde body, with the exception of aur. B<Hie, 
muscular flesh, blood, membrane, &c. are all heavier than water ; 



9R Mr Dtltoo'i Phynological Invet^a^otu on 

anbml fiit is perhaps the lightest of the componenta, but even 
this is heavier specifically than the whole man upon the aiverage. 
Bone from the 1^ of a calf I found to be i.S4 specific gnTit;'. 
The lean of beef (raw) I fbuod 1.045 specific gravity. Blood 
is from l.OS to 1.06 specific gravity according to circumstaDces. 
On the whole, the solid and liquid parts of the body, examined 
after life is extinct, would appear on an aversge to be aoraewhere 
about 5 per cent, heavter than water. 

That part of the volume of man which is exclunvely occupied 
by air, and which may therefore be considered as adding naAing 
matmslly to the weight of the bfidy, oonsists of the lur^tabes 
and air-cells of the lungs, the trachea or windpipe, the mouth 
and othn appendages. It is not easy to ascertwn the n»diunaf 
volume of ur in the lungs of any individual. Messrs Allen and 
Pepys found the air remaining in the lungs of a man after death 
MMnewhat exceeded 100 cubic inchcR. I found fwmerly that 
after a full inspiration 1 could blow out SOO cubic inches of air 
firom my lungs, but was then quite exhausted. My ordinary in- 
spirations and exfnralioits amounted each to about 30 cubic 
inches *. 

Judging from the above facta and considovtions, I diould 
be disposed to condude that the medium vtdume of air in the 
lungu of a middle-aized person would not be less, hut rather 
moro, than 100 cubic inches. Be^des the lungs there are no 
other receptacles for mr, I believe, in the body except the sto- 
mach and bowels, which are occa»oDally more or less inflated 
with portions of air either from the atmosphere or other sourcesi. 
If we allow 150 cubic inches for the volume of air ootitiuned in 
the wlWe man when entirely immersed in water, it will be as 
&ir an estimate, perhaps, as can be made. But it may be ima- 
^ned by some that the whole substance of the body is pervi* 
ooa to wr; that the skin, the flesh, the blood and even the 
bones, may be imbued with air, somewhat in the same manner 
that water is, and yet have no cavities or ce^ls in which the ur 
is collected into a visible volume. Whether such an idea has 
ever been ^itertained or discussed I am not aware ; but I pre- 
sume no one has succeeded in determining either the nature or 
the quantity of the air so enveloped in the system. We shaH

now examine how far such a ootion ib countenanced by the pre- 
ceding statraiait of facts. 

.According to tiie preceding table of Robertson, the arerige 
bulk of the ten men was S.618 cubic feet, 4.600 cubic int^ies 
nearly ; but of this vt^ume ISO inches according to the above 
cBtimate were air, and the remunder 4860 inches were solid and 
liquid parts of the body. Now the average specific gravity of 
those parts of the body has been estimated above at 1^ whan 
examined as dead matter : this would make thor weight equal 
to 4567 cuIhc inches of water ; whereas it was found by actual 
weighing, to be \46 lbs. as per table, = 4044 cubki inches : hence 
the obsrared wei^t was less than the calculated wagfat, a pw. 
tim equal to the w»ght of 523 cubic inches of wato*, <ur more 
than one-ninth of the whole weight c^ the body. 

Here is a disarepance that demands an investigatiiMi. Can 
Robertson^B table of the specific gravides of men give too low 
an estimate!* This is not likely; every one Imows that the 
human subject generally floats in water till the lungs become 
filled with that element, — a proof that the body is lighter than 
water ; and many persons are observed to swim with the whole 
liead constantly above the surface of the water. 

Have we overrated the specific gn^dtlee of the component 
parts of the body P I think not : bones, and flesh, and blood 
are certainly all heavier than water, some more, sone less. 

Has the capacity of the lungs for air been underrated P I 
cannot imagine that any one will contend that the lungs (^ s 
middle-uzed man will hc^, at a medium state of inflation, six 
times the volume of lur we have asdgned. Upon the whole, I am 
indined to believe the true explanation of the ^fficuUy .will be 
fo\^id m this, that the substance of the bot^ is pervious to air, 
and that a .fonqduable portion of it constantly cnists in the 
body during i^fe^ subject to isorease a,Dd diminution aceordingu 
lo the pressure of the atmosphere ; in the same maimer as it 
exists in water : and, further, that when life is extinct, this air 
ia some degree escapes and renders the parts specifically heavier 
than when the viul functions were in a state of activity. 

The facta that water absorbs air of all kinds, that the quan- 
ta of the air absorbed is prt^rtioned to' the jHVssuFe and den- 
sity of the gas, whether it be alone or mixed with other gases, 



94 Mr Dattoa's Phytiological JwoeHiga^ona on 

and Uilit certuQ laws of equiltbtium take place, by which v^tOB 
acquires that state in which it is disposed neither to give out 
nxa to take in aoy more gas, baTe been abundantly jwoved by 
Dr Henry and mysdf. M- Saussure has shown the hice ibe 
other hquids, and for a great number of sohd bodies. It may 
be seen, too, in my Chemistry, voL i. p. S36, that a bladder, wbkii 
is generally conndered as an animal membrane, least pervious 
to air, may be filled widi one gas, and being some time exposed 
to the atmo^here, it will be found to omtioue fidl Uown as U 
first, but the cooteota will be chiefly atmospheric air. Messrs 
Allen and Fepys, in thor ingenious and exceltrat essays on ree[»> 
ralim, have proved that when a Gtuinea [Hg or a {Mgeon is coD^ 
fined for an hour, more or less, in a mixture of hydrogen and 
oxygen gases, in propivtion as 78 to SS, a large portion of azotic 
gas is found in ^e reudue, and an equal porUon of hydrogen 
disappears. They ascribe this change to effects of respiration, 
but it appears to me more probably due to the principle we are 
advocating ; namely, to the egressof azotic from the whole body, 
and the ingress of hydn^en in lieu of it, in consequence dS with* 
drawing the extenial pressure of the former and substituting 
that of the latter. 

When the palm of the hand is placed over the Xo^ of the 
receiver of an air-pump, and the air is exhausted, the pressure 
of the air on the outmde b scarcely felt, but the inside is swollen 
and feels as if it was drawn or suoked into the receiver. Xbus 
the sensation is on the inude and not without ; but there is 
within, and the consequence is a tendency of the air in the hand 
to escape into the reoeiver, which occasions the pain and swell, 
ing. It is thus also that (he issuing of blood in the suigical 
operation of cufqnng is effected. 

Though it does not seem of much consequence what the 
pressure of the air may be on the animal frapie within certain 
hmits, yet sudden changes must always be accompanied with 
uneasy sensation. Climbing mountains, or ascending in a bal- 
lom, removes a part of the atmospheric pressure from the body ; 
this causes the air in the body to tend outwards, and somedmes ac> 
«asions bleedings. To supply oxygen to the lungs, a greater 
volume of air must be breathed, and this seems to produce an 
occderation of ^e pulse. On the other hand, by descoidiag 



the Almosphmcal Preuure on the Animal Fraiae. 90 
30 or 40 feet deep into the vater ia a £viDg bell, the presBure 
of the air upon the body is increaaed inwards ; painK in the can 
are felt from the difficulty of soddealy restoring a disturbed 
equilibrium ; but if tbe descent is slow and intarupted, time is 
given f CM- tbe air to eaiter tbe pores, and the pain is less seUnblei 
To wbat limit warm-Uooded animids oould bear rar^factiou c^ 
air so as to subsist, has not, that I am aware of, been detenniik 
ed with mudi- predsicm. Ascoits in baUooos have been made 
till the ataio^heric [srasure was reduced more than one-balf; 
Fcnoerly I found that a mouse oould avbaiBt in ^th of atmo* 
tphcnc density and seenied not to have su&red much ; but upon 
reducing tbe dennty bdow ^tb, the animal was coavulsed and 
expired inmiediatdy, notwithstanding the air .was instantly ad- 
mitted. 

If the view we have expounded in this essay, in r^ard to 
the action of aerial pressure on the animal frame, be coirect, 
it may be inferred, that the pressure admits of great latitude ; 
perhaps an animal could subsist under tbe pressure of half an at- 
mosphere, or of three or four, or more atmospberea. The uneasi- 
ness and danger would be found in tbe quick transition ; if time is 
allowed for the ^r to enter the body, and to escape from it, the 
transition is gradual, and the sensation arising from it imper- 
ceptible. The animal economy would be adapted to it, like as 
in the transition from a cold to a warm climate. It may here- 
after be found, what length of time b sufficient to adjust the 
equilibrium, and whether this subject is any way connected with 
certain diseased states of the body. As far as regards the al>- 
Bolute pressure on the body, and our insensibility of it generally, 
this question will be met by the argument, that the ^r within 
the body, by its elasticity, sustains a corresponding pressure 
from without ; but this only accounts for our alleviation from a 
small fractional part of the whole exterior pressure. The great- 
er part must still be supported by the body ; and we must have 
recourse to the great incompressibility of matter to account for 
our insennbility of pressure. Canton found that water, pressed 
by one atmosphere more than ordinary, only exhibited a reduc- 
tion of BiTTO^h pan of the whole; if the same rate, applied to 
the compression of the human body, the reduction or comprea- 
uon of the size of a man, 4500 cubic inches, would only be Jth

satisfactory and cwdistent experiments, tt^ipreviously assumed 
law, that the force of magnetic attraction and repui^n is in 
the inverse ratio of the squares of the distance. The applica- 
tion of this law to the invesUgation in hand served at once to 
verify the law, and to render the results of my experiments of 
general application. In regard to the comparison of distances, 
it appeared to me to be of considerable advantage to estimate all 
distances in len^ht of the bar made use of, by which the re- 
sultfl for any one bar becarof applicable to all other bars o£ a 
proportional form and quality, and state of magnetic energy. 
And tuch, therefcH^, with a certain pioiMcaticai, afterwards 
found to be necessary, was the measure constantly adopted. 

Pladng now the magnet in the direction of the east or west 
point of the compass, or at right angles to the magnetic meri- 
dian, I proceeded to ascertain experimentally the deviations pro- 
duced, either by the same pole constantly, or by the mean of 
the actjon of each pole alternately, first at the distance of one 
length, and tlieu eueceesively at other distances to the extent of 
ten lengths of the bar. 

Preparatory, however, to a general apfJicalion of the results 
thus obtained, it will he useful to ascertain by calculation the 
actual force exerted by any magnet on a compass at different 
distances, according to the above law of attractions.

As the results ia the 6th coTomn appeared to differ too'eaa- 
, Eideiably to be at all satisfactory, the last thi%e cdlumbs'wfTe

^parent, divcrepancies. Taknig the maaa of the ra^os at 
7M0O, in round nuraberB (which was found to be snffrcieriHy 
Jiear the truth), and applying that in a contrary nay to ^he 
.magnetic forces belong^pg to the different distances, the column 
.of " calculated tangents'" was obtained, the resulting angles of 
vhich, with only one or two exceptions, correspond with those 
obtained by experiment within the probable limits of error of 
..^beervatien*. , , 

* The compass emplojed being onl^ gTMduMed to 30" of rdegi^e, ^d 
without iny TerdleT, it requlied some habit and attention to observe the «n. 
gW tAthin tudi nnall litnita w thove indicated by the column of difiermcc*-

These results, however, though sufficiently unircH-m and con- 
J -slstinrfcniroBt ■practical pnrpo a e a con n ecte J -witluhe preemt ■ 
< investigaUoDs, were not so entirely satisfactory as to be received 
fllSijp«»tcIusive. Por-the differeeee b«tw«en the observed and cal- 
tiulated deviations at the first distance was by far too conuderable 
to be ascribed to any error of observation ot other accidental cir- 
cumstaoce, «ince it was proved to be occusioned by some con- 
stant^ aioUi^ CMU^i h«cause cf a aiaiilsr discrepancy being al- 
ways found to occur through an extensive series of experiments 
with ioaany different magnets. 

, TV ^iscrepaijcjes beyond the mere errors of observation were 
at length discovered to be mainly owing to the adoption of ex- 
act lAgths of like mfignets as integers of distance, instead of the 
l^tgtl^ of the interval between what may be tamed the fid qf 
attracHou in the north and south portions of the bar. For, al- 
-thbugl^ tb» prguiipat enfg^ of a well constructed and well mag^ 
netized bar is doubts at the extremities, yet a considerable 
though rapidly diminishing power necessarily prevails atthin 
th^ «Kti)emitiea. ^ The (^gregate or reiultant action, therefore, 
I cf the vtayiag int«Dsities of ptfaer -half of the bar may be rc-

' la* order 'to determine the position of thg'foci of attraction 
iti a three-feet bta'-magnet (A) of very superior construction, I 
assumed, in the first ipstabce, the Jbcal length to be S &et 30 
inches, considering the foci of attraction to lie an inch within 
the extremities of the bat. In this case th^ "-Difference" intha 
first length, which in the preceding instance was 2° 14', (Col. 9.) 
jWasDowreduced to'lesa'Jhan bn^-hatf. Afocal Isn^h of 3feet 
y inchci was then. U^ed, ftben aforthet* teduotioti of error was 
observed. Lastly, I assumed the distance between the 'foci to 
"' be'sife^' 6 inches, arid iheii the results were roo* iftikirtgly 
■^ ccmsistent and satisfaictory.

In all my previous experiment!, which amounted to fioin. 
fiiWn to twenty Series, the tangent of the angle of c!eviation, 
at the distance of the first length of the bar, was always consi- 
derably ieS8 iKan'tlie mean of the column of ratios, I^ecause of 
the assumed )ength between the foci of the m^ignet |bring too 
great ; but ifa this last series, for the first time, the fatigent be- 
longing to dne focaUength's disui^e is somewhat ^ great, 
which might seen) t9 indicate Uiat the aq^upied Jlengtli was now 
too small. Where,ibpwewer,:a)l the rati«s at otber ^isiaoces are

The compaSB, id the next trial, was placed upon the library 
chimney-piece, and the needle bo far neiilralized, that its vibra. 
tions were reduced from IS to 8 per minute. ' A pur of two 
IWt magnetB were then taken to the farther extremity of a bed^ 
room GO the same floor, sep«rated from the compass by the 
width of two rooms and a lobby, with two brick-walle, book- 
case containing books, &c. ; and there, in a parallel position, 
and about 10 inches asunder, presented to the compass. I'heitf 
action, though at the distance of 31 fert 8 inches, was quite evi-, 
dent and measurable. The amount of the influence of Uieic 
poles, in a mean of six sets of experiments, waa O^.S^'J *, 

Having at this stage of my experiments ubtained a beautiful 
pwrof magnets (A), before referred to, from Sheffield, construct- 
ed under the kind superintendence of Mr Abraham, I was en- 
abled to accomplish every thing which my calculations had anti- 
cipated. These magnets measure exactly 3 feet in length, %\\\x 
im:beB in breadth, and |th of an inch in thickness. They are 
made out of the best cast-steel, and tempered throughout,— the 
ends, after the whde.was hardened, having be«i seduced to a 
gold colour, and the rest of the hars to a blue. The following 
table exhibits their powers in combination, as they^lie in thdr 
case, 4i\ inches asunder, in that reduced stale of magnetism pro- 
duced by being repeatedly pUced in unfavourable cmitact ; when, 
magnetised, however, to saturation, their action on the compass 
is still more consideiable. 

• In very delicate experimeuts, it is found to be advanlageoua to the «c- 
tion of tbe compasfi gently to tap the glass with the point of the finger;' 
without tills precaution, the friction of the ueedle on Its point may be i«ti- 
ductive of Goniideabk diseref«Dde&

116 Rev. Mr ScoreBby on the Unifi>rm PervteabiUfif 

With these magaets the fgllowing experiments, shewing their 
influence through aiAiA substances, were made. 

Near the engine-house of the Liverpool' and Manchester Rffil^ 
way, I found a very favourable position for trying the effect of 
the'magnetic influence on the compass, through a soKd mass of . 
freestone rock in situ. In the place referred to, the rock is ex- 
cavated in two parallel positions to a considerable depth into th* 
■olid. Between the two is a solid septum 31 feet 5 inches iii 
thickness. The magnets being placed on the one side, and the 
compass on the other, the position of the needle, (which happen- 
ed to be so nearly parallel to the wall as to require no directing 
magnet), was observed, and then the opposite poles of the mag- 
net were presented, which occasioned a deviation of about J of 
a degree. The experiment was repeated several times with d 
very uiuform result, affording a mean deviation, being the snni 
of the action of the north and south poles, of about SO" of a de-

distance of 33 feet 1 inch, viz. 31 feet 5 inches of rock, and 8

On a subsequent occasion, I attempted to transmit the mag< 
netic influence through about 60 feet of rock near the same pUce 
as that of the above experiment ; but the quantity of " Kve-

ly passing to and fro, produced such frequent changes on the 
compass as to defeat my object in this experiment. In conse. 
quence of this disappointment, I sought in my own premises for 
a sitnation suited for my purpose, which the sloping nature of 
the ground in front of the house readily presented. Placing the 
magnets in the front garden, and the compass within the house 
in a cellar kitchen, the magnetic influence had to pass obliquely 
through an extent of soil, stones, and brick-walls, of no less 
than 61 feet, in order to act on the compass. But even at tluA 
distance its influence was very perceptible. The mean of. ux 
experiments indicated a deviation under the action of theoppo-,

The foregoing investigations, defective as they are in attain, 
able accuracy, are nevertheless amply sufficient for the practical 
application of the present method qf determinvng the thicknesa 
afsdid substances, not ot?terwise rr^easurable- 

The cases in which this mode of measuring dbtaoces seems 
to be most particularly suitable, and where, it appears to me, 
its application might often be of considerable importance, chiefly 
occur, in mining. 



1 18 Rev. Mr Scoresby on the Uni/brm Perineabiiity 

In tunnelling, for instance, through rock, and working from 
difierent shafts, this method of measuring the intermediate dis- 
tance would often relieve the engineer from much anxiety, and 
the miner from much personal risk, when the opposite workings 
come near together. For although practical men, who have- 
been well eicperienced in mining operations, in that particular 
kind of rock, may make a tolerable guess of the distance be- 
tween the two *' head-ways " previous to their breaking 
through, yet, it is well known, that very experienced en^- 
neers have often estimated the interposed HMik at some yards in 
thickness, when, in reality, it has not been more than as many 
feet. Blasting, under such a false supposition, it may be well 
imagined, might be attended with the most fatal consequences. 

A very serious accident, that had well nigh proved fatal to 
two very deserving men, happened in the working of the r^- 
way tunnel under the town of Liverpool, which will very well 
illustrate the present case. This tunnel, which is SSfiO yards 
in length, was excavated not only from the extremities, but also 
from six or seven intermediate shafts. The person entrusted 
with the superintendence of the working department, being a 
practical man, was aware of their near approach to a junction, 
and arranged a signal with the opposite party previous to their 
making an intended blast. But the workman charged with this 
duty, it would seem, did not believe that the junction was bo 
near, for whilst the confiding " overlooker," and a companion 
on the opposite side, were listening to the sound of the picks, 
the thoughdess miner, without giving the signal, applied the 
match, when the force of the discharge, instead of re-actipg, ex- 
ploded forward about the defenceless heads of the unfortunate 
individuals in the contiguous head-way. Most providentially, 
they escaped with their lives ; but they were severely wounded, 
their faces permanently blackened by the penetration of unex- 
ploded gunpowder, and both of them suffered the loss of an 
eye ! 

In this instance, had the distance been accurately determined, 
which it might have been by the magnetic inBuence to withiu a 
quarter of an inch, they never would have attempted a blast un- 
der such perilous circumstances, or at least no man would have 
been so reckless of the safety of his fellow- workmen, as to have 
uade the discharge without a sufficient warning.

Anotfaer impartuit applicatiM) of the prapoeed method of as- 
certakiing dutaaces, is in the working of mines.. When ap- 
pcoaGbing an old working Jrom a difl^nt shaft, or the verge of 
an adjoining mine — peHbaps a different properly, — many re- 
sons might exiat. moh as an accumulation . of water, " fire^

wbikt, on the oUier band, the value of the ore or bed bf coal 
vaigiht be such a« to render it dedrable to approach as n^t as 
Qooustent with safety. No means, however, heretofore known, 
would enaUe the miner to ascertain with accuracy the thickness 
<tf the iotcrposing wall ; whereas, by the proposed ntethod, when- 
ev£r the two sides of Ute wall were attainable, the thickness^ 
within given limits, mt^t ea^ly be determined. And the cases 
in by no means untrequent, in which a magnet, under propel! 
piqcautionB, might be safely carried into an old working (km- 
taioing fire-damp or water, though the breaking through into 
that working might be attended with most ntischieTouB or even 
dongeious consequraces. i 

In mining beneath ibe sea also, or iinder the bed of a river, 
the same principle (substituting a dipping-needle for the com- 
pass) may be easily applied, so as to det»muie the thickneaa of- 
the stratum of earth or rock forauDg the roof of the mine, and 
indicative of the sufficiency bf the pcotedion against overwhelm-

Maiiy supposAUe cates might occur in engioemtig, or iii or-, 
dinary arobitecturat works, in which the prindple before us 
vimild Jutre important application. Suppose, for instance, that 
it ia proposed to built} a spi/e upon the tower of a church, or. 
any other heavy superstructioe upon a f^ven wall, but it is riot 
known, frqm tb4 wiutt. of embrasures or windows in some of the 
sides of. ibe. tower, wbetbcir each portion of the basement be

perforetitig the wail, wbe^ no ordinary means exist of ascer-. 
taining ita thickness, nbich might be laborious, and perh^ a 
bIfiOalah to the intbrwrj,.tbc magnet would t-eaditv give die 
thickness to the greatest desirable accuracy. In like manner, in 
eiijpqfering, the tbiokoesd of waits, or beds <^ rock, - not other.^ - 
wiEie determinable but by actual perforation, might, in most- 
suptteeable cose^ be measured by means of tHe magnetic devia-

Mr George Stephenton, the talented edginecv of the Xkiit-

which, he conceived, might frequently be. exceedingly oseEul' in 
the woiiing of coal. In many cskb it is the practice uf -thf 
cdliers to run two parallel drifts thraugb a great extent ctf 
coal, leaving between them a wall, from 10 to SO feet tbick^ 
for the support of the roof, but which it is desirable should not 
be thicker than necessary, to prevent the waste of labour and 
coal. In this arrangement, which is often adopted wben tbe 
roof is loose, so as not eaEaly to be supported, it is a matter of 
g^eat practical difficulty to prevail an undue Microachment upon 
tbe limited thickness, that the safety of .the roof be not «DdaB- 
gered. In such a case, the apparatus for tbe deviabon might 
be applied with much advantage, and the thickness verified, as 
occasion might require. 

An ^gineo' in extensive practice in Scotland, who recently 
visited Liverpool, and happmed: to be present at the '' raflway

It still remnna for irie to ileacribe tbe requisite apparatus, 
with the praparatino of the iDAgnet% and to ofier & few saggar 
1JQI16 ior carrying into the practice of mining, &C. the priiunfHra 
developed by the preceding investigaticMs. 
' The apparatus necevaiy for the practioal objects in view are 
flbieflf a pair of bar magnets, tempered throughout, a£ 6 feet or 
□pvards in length ; another pwr, say of IS iuAes, correapoad' 
ing id quality, temper, and proportions; a ccmpass (tbe one ' 
eiDfJoyed for mining operations will do), with two or three oth» 
articles, of simple structure, hereafter to be described, wbi<A 
may be made by any ordinary artizans. The preparatioa and 
determination of the powers of the magnets will be the first step. 
. HI the business. 

The bars having been liiagnetized to aaturatioQ, will require 
to have their directive powers and foci of attraction determined. 
Previous to this, it will be prudent to pl&ce them upon one ano- 
ther for a few moments, with similar poles contiguous, not in 
contact, but sepamted by a sheet of paper, or other tbia sub- 
stance, in order to disperse or neutralize any excess of m^netic 
energy which they might not be able permanently to retain. 
Without this or some similar precaution, the intensity of the 
Hutgnetic energy of the bars will be liable to diminution in the 
course of the experiments, so as to prevent satisfactory of ii^ 
deed useful results. The position of the foci of attraction may 
then be eadly det^mined. And in accomplishing this, tor ordt: 
aary pracdoe, it will only be necessary to try the deviation at^the 
first three or four lenglhe. Assuming the focal position, as In tbe 
experiments heretofore made, at ^'gth of the whole length from 
each extremity, we shall generally, in properly magnetized and. 
w(U-pr(^)ortioned bws, be very near the truth. 
- But, by the way of example, let the poMtiou of .the foci e( 
Attraction of a thret-fea bar^ or of a pw of audi magnets ia 
combination, be r^qtrircd. The assumed pontion oS tbe foci gf 
attraction, at ^gth the length within each extremity, will give 
SI fdet 6 inebce for tbe focal len^h, and 3 inches for the disttUlce 
(^ eii^ focus frcna the extremity. The first focal. Imgtb, bt^'

vaticKi, of the two poles of the magnet at these several dtstaace^ 
and multiply the taogent of the deviations by the reciprocals of 
the relative forces beSote determined (Tables at pp. 99 and Hi!) ; 
then, if the amumed pontion of the foci be correct, tlie numbers 
thus obtained will corre^wnd very nearly with the tangent of 
the angle of the greatest deviaUon, as well as with each other. 
If, however, the tangent of the greatest deviation be lea* than 
these remoter products, then the assumed pontioti of the (bd 
will be too near the extremity of the magnet ; but if the nearest 
tangent be ven/ tmich greater than the rest (we speak here of a 
3>feet magnet), then the poution assumed will be too far from 
the pole. As, from principles already explained, the first tan- 
gent ought to be somewhat greats than the products of the 
other tangents*, it will be dearable, when a tolerably close ap- 
proximatioD has been obtained, to verify the result by trying 
the deviations at greater distances. 

What has been now suggested for the determination of rfie 
foci of attraction, is equally applicable to two or more bars in 
fixed ccmibination, or at a given distance, as to single bars. A 
cOuvenient arrangement, represented in Fig. 6, decdgiled for the 
safe keejMng of the magnets and their employment in practidd 
operations, will be well adapted for giving fixedness of portion 
during the determination of th^r povera. Here, cbe magnets 
A 1, A 3, are laid in parallel grooves to a case about ftmr iochet 
apart. C, C,aretheneutraliring conductors of soft iron,whicb^ 
uniting the opposite poles of the magnets «ben not in use, serve 
to preserve th«r energy umnjured. a a are two pieoea of wood 
fitted into grooves in the centre of the case, of the same size as 
the cooductora Such is the anangieitteDt when the bars are 
Required to be neutralised, and always when unemployed; 
"When required in the mine, it is only necessary to change the 
posiuon of one of the bars end for end, so that the two similar

ductors into die grooves at aa, and substituting in theii stead 
the pieces of wood ; b; this means the tn^nets are retained 
firmly in their places, and the whute apparatus kept together. 

Whilst thus retained in their case, the powers and the .focal 
position of both bars toj^her are determined, so that their fxm- 
dition in practical operations is exactly the same. A table of 
their powers (after the manner of that given in page llfi) may 
then be calculated, and the bars forthwith employed as occaqon 
may require. 

But I proceed with some su^estions for the practical appli- 
cation of the foregoing principles and investigation in mining. 

in all cases where both the level and direction of the work- 
ings or mines are known to be the same, or in which the differ- 
ence can be satisfactorily ascertained, the application of the 
proposed process for determining the thickness of interpo^og 
substances, will be. sufficiently plain from what has already be«i 
stated ; for, in such cases, a single observation of die deviation 
produced by the action of one or more magnets will be sufficient 
to show the distance betwist the magnet and the co.mpaBS. 
When the direction of the separating wall lies nearly north and 
south, so that the compass does not require any directing mo^ 
net, the table of deviations already cakuUted for the msgneta 
io use will enable the miner generally to judge with sulQcient 
accuracy of the distance, without the trouble of bringing the 
magnets round to make the corresponding experiment*. And 
even where a directing or neutralizing magnet is employed, it 
would not be difficult to come at very satisfaotory results by th« 
employment of the ^nailer set f£ pn^Mrlional magnets (prp|)(M'- . 
tional as to dimensions and directive power), so as generally to 
render it unnecessary to remove the bars from one mine to the 
piber. For if the two pairs of bars.wo^ coostruicted at the suae 
time, of the same quality of metal, and of similar temper, there 

* Should the proposed plan of measuriog the thickness nf rock, &c. be 
brought into general practice, it would be lueAU and important to have triile*

vould be little difficulty of giving them a direcdre power, which, 
at considerable distances, in reference to tbdr focal lengthv 
would be very nearly, or almost exactly, the same; and, indeed, 
were there some little difference in the magnetic intensity ot the. 
two sets of bare, it would be no difficult matter to ascertain the 
relative force of each, and to obtain sufficiently accurate results, 
by calculation, accordingly. The appropriation of the results 
obtained from the smaller set of magnets for the determination 
of the distance of the larger magnets from the compass, when 
the same deviaUon was produced, would be most simple — the 
measure of the distance given by the smaller magnets being to 
the real distance through the rock, as the focal length of the 
smaller is to that of the larger magnets. If, indeed, the smaller 
magnets were a foot, and the larger three feet in length, the 
distances at which they would produce equal deviations, suppos- 
ing their magnetic energy proportional, would be just as one to 
three. 

Another method might be adopted for reducing the observed 
deviation under a neutralizing or directing needle to the ratio in 
the table of deviations, which is by finding the number of oscil- 
lations of the compass needle in a given time, after its adjust- 
ment in the mine, and by comparison with its ordinary vibra- 
tions under terrestrial magnetism only, calculating the relative 
magnetic forces contending against the actioa of the magnet *. 
Bat this method being troublesome, the former is to be preferred 
for ordinary practice. 

As in many cases, however, the comparative levels or direc- 
tions of the two worliings might not be satisfactorily known, a 
single experiment, though it give the distance between the com-' 
pass and the magnet, will not be sufficient to determine the nearest 
approximation of the two contiguous mines ; but the nearest 
approximation, I apprehend, may be very well determined, and 
at the same time, — a matter of no mean importance, — the com- 
parison of level and direction, as well as the distance of the 
woridogs. It may be useful, however, for the sake of perspi-

cuity and practice, to consder this application of the principle 
under three separate cases. 

Cask I. — Where Ihe level 0/ the mines is htonn to be the same, but 
the direction is dtmbtfiU. 

In this case it is only necessary to apply the magnets in one 
of the mines in a given position, and then at the same horizontal 
level of the other, (say on the floor of the mine, or at any par- 
ticular distance above), to try the deviations of the compass at 
moderate intervals, from side to side, directly across the head- 
way, when, from the observation of the greatest deviation, the 
point nearest to the magnets may be ascertained. One precau- 
tion, however, will be necessary. If the direction of the com- 
pass-needle be not exactly at right angles to the portion of the 
magnet, then the greatest deviation will not occur at the nearest 
point but a little beyond, towards the place where the action of 
the magnet is most perfectly tangential *. Hence, it will be 
generally advisable, not only to adjust theneedleof the compass, 
by a directing magnet, as near as may be to a right-angular 
position with the magnet (as shown by the known magnetic 
position of each mine), but also to repeat each experiment with 
both poles of the magnet alternately presented to the compass, 
so as to obtain the difference of deviations of the two poles 
at each position of the compass. In order to conduct this ex- 
periment with the greater fadlity and uniformity of effect, the 
simple apparatus represented in Fig. 7, Plate V. of preceding 
volume, fanned out of a piece of board, may be useful.

oppcBite side, when the compass apparatus, guided by the 
batten e e, being carried trom side to »de, will shew the great* 
est deviation in the position a. Let the magnets be now turiied 
with their opposite pole towards the compass, (the time for doing 
which is to be indicated by signal, as about to be suggested), and 
the deviations tried a second time across the mine. If the. 
greatest deviation be in the same position as before, ihcU may be 
assumed as the nearest pnnt ; if not, the mean of the two por- 
tions must be taken. 

It is not necessary to describe the experiments more rainute- 
^, nor to enter into the management of the apparatus for all 
particular cc^tions ; for to do so wouM swell this paper to an 
i&convenientiil&igth, whilst the details would be easily anticipa- 
ted by a very little practice. It may be proper, however, to 
mention, that where the deviations on the removal of the coa^ 
pass continue to increase to the very extremity of the board, oi: 
to the side of the headway, it will, be necessary to cause the mag- 
net to be. removed in the opposite direction, ao that the^maxi- 
tavm deviation may be satisfactorily obbuoed.

1*8 Rev. Mr Score^y on the Unifimn PermeabiH^ of 

Case II. — Where the directum maybe certain, but the level doubtful. 

Here the magnet and compass being placed oo the known 

. line of direction, the compass is moved progressively upward, 

from the floor to the roof of the mine, to deteroune the greatest 

deviation, which, it is evident, will be on the same horizontal 

level as that of the magnet. 

A result, perhaps more satiafactory, might be obtained by the 
use of a needle, suspended like a dipping needle, and traversing 
in a vertical plane. Such a needle being brought into a vertical 
portion by a small directing magnet, would shew by its devia- 
tions the posJbon of corresponding level. 

Case III.'— Where both level and direction may be uncertain. 
In this instance, the magnet being fixed, and the ptank placed 
on the floor of the mine, the compass apparatus is to be car- 
ried from side to side, till the place of the greatest deviation 
is ascertained, or the middle between the two posilions of great- 
est deviation produced by the different poles. This will give 
the directional position. The vertical needle being now tried 
throughout a vertical line drawn through the directional point, 
will shew by its greatest deviation the horizontal level of the 
magnet, which, being at the same time in the directional line, 
will indicate the nearest attunable point between the magnet 
and compass. The vertical needle, in this and similar cases, 
may be guided in its transit by a board, with a straight edge, 
or pillar of wood, placed vertically, so as to preserve its paraU 
Idjsm of portion at every altitude. 

It may be proper here to call to mind, that the chief object 
of the processes now described, is the deternuudon of the 
thickness of solid substances not otherwise mdlurable, and 
not. primarily at least, the determination of directicm and levels ; 
tot the application of the observaticai of deviations to, these 
latter purposes is only expected to afibrd an approximation, 
in some cases, indeed, a very important approximadon, to the 
truth. Where the distance to be n^easured is small, «By only 8 
or 10 feet, or in any case in which the deviatiwis amount to 9 
or i degrees,— the hne of direction may be very accurately d^ 
termined by the middle point between the maximum deviattoos 



of the opponte pt^ of the magnets, and especially if each ttutxi- 
maia be itself determined by the mean of equai devialiom oa 
both Bides of the maximum; in iJmcase 1 have frequently de- 
tenained, at moderate distancea, the very point on tbe ttait 
{Jank, from whence a line drawn at right angles will pass through 
the magnets, coneequently the nearest possible distance between 
the mBgnet» and compass. Where the deviations, however, are 
very small, as it will then require a eonsidmtble change in the 
positioa of the compass, laterally, to produce any sensible dumge 
in the deviation^T— the line of direction, or the level, will be pro- 
portionally less certain, though the nearest distance may be svS~ 
ficiently ascertained. 

As the person who conducts any e^cperiments on the forgoing 
prindples will have to direct \he application of the magneu, 
villi any changes that may be requinte as to their poles or posi- 
tioo, whilst the experiment is in pr<^ress; an arrangement of 
directions by signal will be necessary ; and this may be very 
well accomplished by the blows of a hammer or mall. 

The distance at which any sound can be heard throu^ solid 
flubstftnces, wilt depend both on the nature of the concussion, 
and the quality of the vibrating mass. Through earth, gravel, 
or other louse materials, the transmis^on of sound is very> li- 
mited and uncert^n ; but throu^ solid uniform rock, direc- 
tions may be communicated by signals to very con«derabIe dis- 
tuices. In solid and uniform sandstone, the pick, T understand, 
. may be very well heard through a distance of fifteen or sixteen 
yards, whilst the vibration produced by a blast may be percei- 
ved at very great distances beyond. The working of coal by 
the pick may be generally heard ^sty or eighty feiet, I am told ; 
though no rational determination of the thickness can be made 
fnmi the nature or intensity of the sound, — for a change in the 
structure of the bed, or the interpontion of an increased quaa- 
thy of mcnsture, may produce as great an alteration in the sound 
as might be' expected if the distance were doubled ! The blow 
(rf* a mall upon an iron wedge set in the rock, may be beard 
Aiach farther than the stroke of a pick, or the blow of the hea- 
viest hammer on the face of the rock, — and this wiH form a 
convenient arrangement for the purpose of ^gnals.

And by such b code it vould be perfectly eaiy for the coq- 

ductoi of the experiment to give vwery requiNte direcUon for 

the application of the magnets, at any distance to which the 

blows could be distinctly heard. 

At distances, however, beyond the limits of communicable 
vibrations, the application of the magnets must be by preooa- 
certed arrangement. In this case a certain moment of time 
might be agreed uptm for the application of the magnets ; and 
given intervals arranged when the magnets ^ould be reversedl, 
and when neutralized. 

Though, ia the [Hvceding investigsdons, the equal permeabi- 
lily vi solid substances generally has been verified or assumed, 
nothing has yet been stated in respect to the effect of the inter- 
position of metallic iron on the action of the magnet. This sub- 
stance, the action of which on the magnetic needle is so peculiar, 
has indeed been made the sul^ect of very particular and diligent 
invesligatioD, but the results have been intentionally omitted, 
both because these results are Eomewhat different from all the 
others, and because ircm, in a metallic state, is not likely to be 
met with in mining, so as in any way to affect the universality of 
application of the process herein suggested for the measurement 
of distances otherwiw indeterminable

ther in steel tempered or soft, does not prevent the influence of 
ihe magnet being transmitted to the compass; but, on the con- 
trary, I have most commonly found, that the deviations produ- 
ced by the magnet acting through a. mass of iron, are greater 
than when nothing whatever is interposed. I have also found 
that the ioflaence is not interrupted, though the interposed me- 
tal be a mass of hardened steel, nor even when trial was made 
on a body of powerfully magnetic bars, two or three inches in 
s(^d thickness. When the mass of iron is not otherwise magne* 
Uc than as to its magnetism of position derived from the earth, 
then the action of a magnet passed through "ks neutral or equa- 
torial plane, is, in all cases, (as far at least as can be inferred . 
from very many trials), more energetic than when no such sub- 
stance is near it This was so particularly the case when the 
magnetic influence was passed through tlie two double cylin- 
ders and furnace of a locomotive steam-engine (conasting of 
ten successive plates of iron, forming a total of 5| inches.in 
thickness of metal), that it required the magnets to be a foot 
nearer to the compass in free space, than when placed beytHid 
the engine, to produce equal deviations. For, whilst tbfe dis- 
tance of the magnets and compas^ when the influencewas tcaa^ 
mitted through the engine, was 7 feet 8 inches, the distance oa 
the open side, producing the same deviation, was 6 feet 7} 
inches *, 

Now this anomaly may be easily shewn to arise from the de- 
velopment of magnetism in the mass of iron, through the proxi- 
mity of the magnets, by which the direct or permeable influence 
of the magnet is necessstrily augmented; but that the whole of 
the effect which takes place is not due to this cause,-— what is 
generally called " induced magnetism," — but chiefly to the ac- 
tual transmission of influence through the very substance of the 
mass of iron, I have di^inctly and experimentally determined. 

■ Some working snj^eerd, who were present when this experiment wu 
made, were exceedingly inquisitive alMUt the eff^ts produced, watcbing the 
deviationaof thecompasn with great astonislRneDt. One of them peiceiring 
that the magnet, which waa hid from his view by the engin-e, equally afiected 
ttie compass as when presented in the open space, addressed himself to his 
comrade, and made this characteristic remark, — " Why, Tom," aaid he, " it 
sees through't !"

±v the earliest stages of society, so many and such great diffi- 
culties were opposed to the use of all nietallic. substancest that 
the discovery and application of them to the purptHes of socia) 
life must have been slow and gradual. 

The most ancient records of our race, the Sacred Writings, 
as well as the works of the earliest profane authors, have, how-, 
ever, communicated such intimations of the knowledge and 
adaptation of the more precious metals to the use of mankind, 
as tends to excite curiosity and to attract attention to the aubr 
jeot. 

The genera) voice of antiquity affirms, that gold, uLver, and 
copper, or brass (aes), were the first metals diecoverod; and 
that they were used partly as oraaments, and putly a» instru- 
ments of war or of industry ; foe though, from th^( softness,, 
they were not the best oalculat9d fot the latter -pwfMseet they 
were better adapted to them than those implements of flint oc 
other hard stones or hard wood, which had been before uscdl^

the most ancient tribes, and which were alao found ftuong the 
savage peojde inhabiting Au!>tralia, who were disoovered in the 
middle «f the last century. 

A well-known passage in Hesiod affirms, that, in remote ages, 
" The earth was worked with brass, because iron had not been 
discovered ;" and Lucretius bears testimony to the same par- 
port, in book S. 1. 1386: 

" £t prior aerii erat, ^uatn feiri, cognitua usm." 

'jL%i3 ia confirmed by the implements of cof^r found in tiie 
ancient mines, which will be hereafter noticed, in Siberia and 
Nubia; whose' woHcing must b^ve ceased some Uiousaod years 
ago. 

When Brazil was first discovered by the Pmluguese, the 
rude inhabitants used fish-hooks of gold, but had not iron, 
though their soil abounded in that metal. The people in Hi»> 
panitJa and Mexico were, in like manner, uDacqiiainted with 
iroo when first visited by the Spaniards ; though they had both 
ornaments and bnplements of gold, and weapmB of copper, 
nAidi tatter, as we learn from the uialysis of Humboldt, they 
bad acquired the art of hardening by an alloy of tin. 

This subject has been illustrated in Denmark, by opening- 
many Scandinavian tumuli of very remote ages, from which 
have been collected specimens of knives, daggers, swords, and 
implements of industry, which are preserved and arranged in 
the Museum of Copenhagen. There are tools of various kinds 
formed of dint or other hard stone, in shapes resembling our 
wedges, axes, chisels, hammers, and knives, which are pre- 
sumed to be those first invented. There are swords, daggers, 
and knives, the blades of which are of gold, whilst an edge of 
iron is formed for the purpose of cutting. Some of the tools 
and weapons are formed principally of copper, with edges of 
iron ; and in many of the implements, the profuse application of 
copper and gold, when contrasted with the parnmony evident 
in the expenditure of iron, seems to prove, that, at the unknown 
period, and among the unknown people who raised the tumuJit 
which antiqutaian research has lately explored, gold, as wdl as 
copper, were much more abundant products than iron. 

Copper, in the more remote ages, was not only commonly,

but in some, if not in all, excluuvely used fbr vaaaey, and at 
these periods may be viewed as one of \he precious metab ; yet 
the dianges that have since taken place have reodered gold and 
8ilv«' more entitled to that name, and vill be so considered in 
the farther progress of this inquiry. 

Some of the eariiest notices which have reached the preMnt 
day of the estimatioa of gold and silver, are in the account of 
the condition of Abraham, the progenitor of the Hebrew peo- 
ple, supposed to have lived two thousand years before our 
ChristiaD era. We read, " that he was rich in cattle, and in 
alver, and in gold*." On the death of his wife, he purchased ft 
field for a burying-place, the payment for which was made with 
four hundred shekels of silver, which he delivered not in coin» 
but " by w^ght, according to the currency of merchants ■|-.'' 

Joseph, the great grandson of Abraham, was sold by his bre- 
thren to a caravan of Arabs, travelling towards Egypt with the 
{M<oductions of thai country, for twenty pieces of silver J. Af- 
terwards, wbni established in 'Eigyipt as minister of the Idng of 
that country, his brothers brought " ^tver in thnr seeks' 
mouths," to purchase com during a season of scarcity in their 
native land. In the interesting sequel of the history of Jos^h^ 
when making lumself known to hik family, be presented to his 
younger and fiivourite brother three hundred pieces of silverg. 

Though gold was known at that early period, and its value 
highly estimated, we find no intimation which can lead to the io- 
f«ence, that it performed the function of money, either by be- 
ing used as the common measure of value for other commodi- 
ties, or by being employed as tiie medium for exchanging one 
kind of goods for another.

Of the AccumidatKm of the precious Metals, from iht most 

remote Jges to the establishment of the Imperial Government 

in Rome. 

There are no inUmation in the Sacred Writings (Hebrews) 
which afford any means of funning an estimate of the whole 
quantity of the precious metals which had been collected in the 
patriardbal days. We must, therefore, rest saUsfied with the 
scanty accounts with which they furnish, and proceed to later 
periods, when the relations of the several accumuli^ions are more 
frequoit, though not marked with any such prea^on as can 
inspire implicit confideoce. 

In the history of the reign of Solomon, as recorded in the 
Book of Kings and in the Chronicles, we find statements of the 
quantities of the precious metals used in the royal palace and the 
hoiy temple erected by that monarch. We read, that " he a\er~ 
laid the house within with pure gold : and he made a partitkm 
by the chains of gold before the oracle, and he overlaid the ora- 
cle with gold. And the whole house he overlaid with gold, until 
he had finished the whole house : also the whole altar, that was 
by the co-acle, be ova-laid with g<^d|." 

The quantity of gold which Solomon collected in a am^ 
year, is stated to be (1 Kings x. 14), six hundred threescore 
and ax taloits, or peihaps about L. 800,000 in value at the 
pcesent mmnent That with which he covered the sanctum 
sanctorum, at the same rate, would amount to above L. SSO,000.

110 Jccumtilation of Wealth wUh Ous Hebrew Nation, 
We learn from the Book of Kings*, ' that the king brought by 
his ^ips from Ophir four hundred and twenty talents of gold* 
or about L. 190,800. The Book of Chroniclesf represents the 
amount greater as four hundred and lifty talents, or L. S09,000, 
a difierence of no great moment, and one which, perhaps, a col- 
lation of manuscripts might reconcile. 

Without attempting to calculate the quan^ty of metallic trea- 
sure heaped up by Solomon, we may best describe it in the lan- 
guage of his day. We read that " his throne was of ivory, 
overlaid with the best gold ; that all the drinking vessels were of 
gtild ; that all the vessels of the forest of T^banon were of pure 
gold : none were of alver, for (hat metal wqs nothing accounted 
oi in the days of Solomon C and, in short, " the king made silver 
to be as stones in Jerusalem ■fT 

After this short intimation of the store of silver and gold ac- 
cumulated by the Hebrew nation, it may be now proper to defer, 
to another branch of the subject, the consideration of the way 
in which such a store of the precious metats may probably have 
been collected under the reign of Solomon. 

In proceeding from the sacred to the profane writers of an- 
tiquity, the reader is naturally in some degree surprised at the 
credulity, or at least apparent credulity, with which the most 
extraordinary and improbable tales are narrated. This is most 
remarkable in Herodotus and Diodorus, who fire yet far from 
unworthy of confidence, where nothing supernatural is concerned. 
The Greek and Roman writers relate prodi^pes, which, at this 
day, we know not whether to attribute to their own credulity, 
or to that of the community for which they composed their 
works. In either case it does not render them utterly un- 
worthy of credit, nor destroy their testimony in matter of his- 
tory, of geography, of manners, of laws, or of government 

llie history pf all ancient nations is filled with prodi^es 
which are no longer believed ; but if, on that account, their 
authority on other subjects be discarded, it will become impos- 
eible to trace the progress of mankind through the several stages 
of society, from the most rude to the most civilized state. It 
is scarcely two centuries since in every part of Europe, with all 
the knowledge and civilization which had been imbibed, the

belief in demoniacal possewions, in the power of witches and 
fairies, and in spectral appearances, universally prevailed. It 
wotild be unjust to the memory of the historiansaod cbronicl^^ 
of that and the preceiUng ages, to reject their testimony, because 
they believed in supernatural events and appearances, which 
- have lost all hold upon the present race, except among the most 
igtHirBnt of the vulgar. 

If, in extracting from the wiiungs of antiquity what relates 
m<H« immediately to the subject of. our inquiry, it should occa- 
sionaliy appear that incredible events are related, the aound 
judgment of the reader will enable him to s^iarate the facts from 
the fictions in which they may be enveloped ; and he may fiad 
€imusemeat, if not iiiatruction, in observing the great credulity 
of the eminent men of antiquity, and in comparing thar habits 
of investigation and discrimination with those of the ablest 
writers of their own age and country. 

Atayria and Persia. — It appears from the rehttions of IKodo- 
rus, that large masses of gold and silver had been collected to- 
gether by NinuB, the founder of Nineveh, " who possessed him- 
sdf of all the treasures of Bactriana, among which there was 
abundance of gold and silver*.^ From the same writer we 
learn that Seiniramb, the wife of Belus, and the successcu' to his 
dominion, who built the city of Babylon, among other stupen- 
dous and almost incredibly magnificent works, erected in that 
rity a temple to Jupiter, or Belu^ ; *' upon which were placed 
the statues of Jupiter, of Juno, and of Rhea, all of beatea gold. 
That of Jupiter was standing upright, was forty feet in height, 
and weighed a thousand Babylonian talents. That of Bhea 
was of the same height, sitting on a throne of gold, having a 
lion on each side of her, and ooe at her knee; and near them 
two vastly- large serpents of silver, weighing.30 talents. The 
statue of Judo was in an erect posture, and wei^d 800 talents. 
An altar was erected for their deities of beaten gold, 40 feet 
tcHig and 15 broad, weighing 500 talents, upon which were 
two cups, each of them weighing 30 talents, and near to them 
aa many censers, weighing SOD talents. There were also three 
drinking vases of gold, the largest pf which was dedicated to

Jupiter, weighing 1800 talent^ and the otber two 600 ulents 
each*." 

As DIodorUB wrote in the Greek language, it is probable be 
adopted the weight of that country, according to which the 
value of this mass of gold, aa calculated by the Abb^ Barthde- 
my, would amount in our money to about L.11,000,000 Ster- 
Ung ; whilst others estimate it at samewhat less, a difference, 
however, searcely worth investigating. It is itnposnble not to 
m^wct the statanent here ^ven of atnne exa^eratimi, though 
we may be induced to brieve that a large quantity of the pre- 
dous metals had been collected at that early period ; but the 
exactness of the quantity must be a subject of doubt, when it 
is conndered that Diodorus wrote near two thousand years after 
the evaits he relates, and in an age when written records must 
have been both rare and of doubtful authenticity. The pro- 
bability of an accumulation of gold to a great extent in Baby- 
lon, is strengthened by the narrative in the book of Daniel, of 
the great size of the image of gold erected by Nebuchadnezzar, 
on the plain of Dura, near that city. 

There is an appearance of authenticity and of accuracy in the 
account given by Herodotus of the tribute of gold and stiver 
which Darius Hystaspes, king of Perna, about 180 years be* 
fore Christ, drew from the several provinces, into which, after 
completing his conquests, he divided his extendve dominions. 
The amount supfdied by each province is stated, and, whether 
paid in silver or gold, " the aggregate sum," he says, " will 
be found to be 9880 talents in silver, and estimating the gold at 
thirteen times the value of the nlver; there will be found, ac- 
cording to the Eubfflc talent, 4680 of these talents. The whole 
bang estimated together, it will appear, thai the annual tribute 
paid to Darius wag 14,fi60 talente f .■" 

This treasure is estimated by Gibbon and by Rennel, to be 
equivalent to about L. 8,860,000 Sterling. According to the 
inference of the former writer, drawn from the same authority, 
in book i. cap. 198, this revenue was the surplus, after the 
expenses of the maintenance of the army, and of the provincial 
administratioD, had been discharged. This quantity of gold and

dver, was probably that which became the property of the mo- 
narch, fomuDg s kind of reserve stock, to meet unforeseen con- 



We find in another passage in Herodotus, a description of 
the manner in which the treasure so collected was [reserved in 
the- royal remdence. " The gold and nlver wfere melted and 
poured into earthen vessels, and the«e when filled were re- 
moved, leaving the metal va a solid mass ; when any was wanted, 
a {Hece was bn^ten off, of the capacity which the occadon re. 
quired •." 

It seemed, as far as r^arded Darius, to be the practice to cmn 
no TOOK QiAA or alver than was needed to conduct the commerce, 
and to defray the expenses of the state "f*, which at that period 
could not be of any large amount, tnm. the paudty of com- 
modities, which were the subjects of exchange, and from the 
low prices which all the necessaries and conveniencies of life 
bore. 

It Ib not improbable that this reserve fund was carefully kept 
from circulation by hoarding, as a preparation for the grand 
camp^gn against the Greeks, which must have formed a part 
of the wariikc operations projected by the Persian monarch and 
lus miniBters. We learn that Xerxes took with him into the 
field so much money and valuable e&ects, as formed loading for 
1200 camels X i and, upon the disastrous events which attended 
his invamon, was under the necessity oS distributing so large sums 
to the mercenary troops which had acoompairied him to the field, 
that Sparta alone received from him 5000 talents §. 

Darius coined peces of gold of great purity, which obtained 
the name of Dorics : th^ were about the value of twenty-five 
shillings of our present money. The name Dane was at subse- 
quent periods, however, given generally to all gold coins which 
contuned but little alloy, and thus indicating the purity of the 
metal, rather than the weight of the piece. The darics of this 
coinage, were few in number, and contracted in circulation, or 
more of them would have been handed down to posterity. It 
is Bud, there are but two now known to exist, one of which is 
in the collection of Lord Pembroke. The figure of an archer is

' Grace. — ^Tbe wealth of Croesus, king of Lydia, 4ho lived 
about 540 years before Christ, has becone proverbUl ; and, 
though no precise communicatioi) of the extent of it has been 
handed down, we may form some esumate of it, by the munili- 
cent present be made to the temple of Delphi, as related by 
HdrodotuB *, and Diodorus'f-, amounting to 4000 talents of siU 
ver, and 370 talents of gold, or near L. 3,000,000 in value of 
our HToney. 

We find in Herodotus a story illustrative both of Ihe wealth 
of this king, and of the manners of his time. When Croesus 
sMit bis Lydians &om Sardis to consult the oracle at Delphi, 
tbey were raoeived with hoapitality by the family of the Alc- 
BMSonidK at' Athens, and, on their return, acquainted tb^r

that fnaily reoeived on iovitBtJon to visit Crcesus, aw} on bis

muntain those horses which guned him tbe victory in the 
Olymfnc games." 

Whatever may have been the real wealth of Cnegus, it would 
appear that gold must have been of very high value in Athens, 
when such a load as an individual could carry about his person, 
in the way here described, could be sufficient to form the founda- 
tion of the fortunes of one c^ t he aristocratical families c^ that state. 

Pytheus, king of the petty toritory of Celeena in Phry^a, 
has been celebrated for his wealth. According to Herodotus, 
he was a native of Lydia« but according to Pliny, of Bithynia ; 
and it docs not appear in what manner he became posaeesed cf 
the rich territory he ruled. It is related of this roan by Hero- 
dotus, tliat, " when Xerxes invaded Greece sixmt 470 years be- 
fore Christ, he entertuned that monarch and bis wholG army 
with great magnificence ; and being asked the lunount of his 
wealth, replied to Xerxes, I conceal nothing from you, and will 
not affect ignorance, but faidy tell you the whole. As soon as 
I heard of your approach to the Grecian Sea, I was desirous of 
giving you money for the war. On examining into the state of 
vay a&irs, I found I was possessed of SOOO talents of silver, 
and 4,000,000, wanting only 7000 staters of gold of Darius ; 
AU tbii I give to you ; my slaves and my &rms will be sufficj^t 
to maintain me." According to the estim^e f^ Larcher, an 
able French criuc, ti^ metallic treasures of this man, the ruler 
of a sniaU tenitory, but the pn^Hnetor of ri(^ mines of nlver, 
anomted t» L. 6^000,000 of ourpr^ent money. 

A long account oi tins man has be«i collected by Larcher, 
diidy fmn the work of Plutamh, " De Virtutibus Mulierum.^ 
It narratea the matures taken by his wife to cure him of that 
pasaon for seeking gold, to which the lives (^ his suli^ects were 
Eacrifieed, and by which a want of sufficient food for subsistMce 
NDSB caused. As the stony has been frequently told, and must 
be faniUav to most readers,, we may di^>«iie with the relation 
of it. The application of the hixati ot all the inhabitants to 
the searcfaing toTy and purifying gold, caused such distress for 
SeoA, that at length Fytbeua was induced to direct, that only 
one-fiiUi, instead of the whole, (^ the citizens should ia future be 
compelled to devote themselv^ to those (^rations. 

Xhe story of Pytheus is important to one of the objects of 
the present ioqmry, inasmuch as it ^ows, as far as it regards

the particular case, that the acquisiticm <rf gold and silver was 

only to be obtained, in that remote period, bj the mines being 

in the hands of severe as well aa arbitrary despots, who spared 

neither the enjoyments, the labour, nor even the Uvea, of thar 

subjects, in the eager pursuit afler the metallic riches of their 

dominioDs. 

It does not appear that the free states of Greece possessed a 
st^ffe of gold and silver, equal to that acquired by these absolute 
rulers of smaller porli(5ns of territory. When Pericles*, in 
ordar to animate the Athenians, in their defence against the 
Peloponnesiaos, about the year 431 befme Christ, addressed 
them, he stated the amount of the money then in the citadel to 
beL.1,162,250; and, in addition to that, the gold in the sta- 
tue of Minerva, which must be replaced if appropriated to the 
public service, to amount to L.1S4,800. The revenues de- 
rived from the tributary states, amoimted annually to the sum 
of L. 116,250, and more than L. 700,000 had been expended 
in improving the public worica f-. 

The mass of the preaous metals brought from the eastern to 
the western world by Alexander, must have been enormous, 
though much of that captured was expended in the sutyugated 
countries, and in those which were between them and Greece. 
The accounts of historians are probably exaggerated ; but what- 
ever allowance may be made lor such a practice wliidi was too 
common with the ancients, ve must be convinced from tbe nu- 
merous authorities * wluch bear testimony to the facts, and cor- 
roborate each other, that the accumulation in the hands of indivi- 
dual monarchs and states, was much greater about the time t^ 
the establishment of the full power of the Roman emjure, than 
any subsequent period. 

The treasures acquired by Alexander in Susa and Peraa, 
exclusive of those which were found in the Pernan camp and 
in Babylon, are stated by the authors above referred to and 
others, by some at 40,000, by othns at 60,000 talents. The trea- 
sure of Feisepcdis is rated at 1^,000 talenu ; that of Pasagarda 
at 6000 ; and upon the capture of Ecbatana, according to the

account preserved in Strabo, 180,000 talents are sud to have 
been collected from tbence, besides 6000 talents which Darius 
had with him, which were taken by the murderers. 

Alexander's profuse expenditure, which his flatterers called 
generosity, was in accordance with the vast sums he seems to 
have acquired. He gave'great rewards to his soldiers, and paid 
their debts, amountiDg to 9800 talenta. He presented to the 
Thessaliaus SOOO talents. The funeral of Hephfestion is said 
to have cost 12,000 talents, and the researches in natural 
history, for the work of Arialotle, 800 talents. The wealth of 
his satraps waa also enormous. Harpalus, one of them, is said to 
have amassed €0,000 talents, although, when at Athens, he 
denied the possession of more than 950. The successors of 
Alexander also collected large sums ; thou^, by their exten»ve 
and fierce wars, the greater part was dis^pated. 

In PolybiuB is found a description of Ecbatana, at a'period 
subsequent to the capture of that place by Alexander, and af- 
terwards in the reigns of Antigonus and Seleucus. 

"The magnificence of the palace," he says, " was such in every 
part as to give a high idea of the power and wealth of those by 
whom it had been erected ; for though the wood was all cypress 
or cedar, no part of it was left naked ; yet the beams, the roofs, 
and the [Hilars that supported the porticoes and peristyles, were 
all covered with plates, some of silver, and some of gold. The 
tiles, likewise, were all of silver. Though the place had been 
three times plundered by those we have named before Antiochus 
arrived, there was still remaining, in the reign of Ena, some pil- 
lars cased with gold, and a large quantity of silver tiles, laid 
together in a heap. There were also some few wedges of gold, 
and a much greater number of silver, l^ese were coined into 
money, and amounted to the sum of about 5000 talents *." 

Ptolemy Philadelphus, the second king of Egypt after Alex- 
ander, IS stated by Appian, upon the authority of official docu- 
ments, to have possessed treasure to the enormous amount of 
740,000 talents; eiUier Soman talents, or the small Ptolemaic 
talent. If Roman talents, which were about equal to the Attic 
talent, be rendered into money of the present day, it will give 
the amount as 178,000,000. If the smaller talent, which seems 
moat correct, be taken, it will amount to at least one-quarter of 
" PoJybiua, bout v, cap. B.— HisU Eoni, Proem. 10.

that sum. Though an account of this kind niaj appear exa^ 
geivted, yet there seems no reason to doubt its gaieral veracity. 
The revenues of the Ftolomies were exccBsively lar^, and the 
countries over which thdr dominions extended were, by the col- 
lections, conif^etely drained of all their wrought gold and al- 
ver ; and the tributes were collected by the farmers of the re- 
venue, with the asEaatance of an armed force, composed not of 
regular soldiers, but of organized bands of robbers. Some idea 
of the degree of ra^iatnty in extracting revenues under Ftolcany, 
may be tbrmed by comparing the tribute drawn from the pro- 
vinces of Ccelesyna, Palestine, and Samaria, under Cyrus, as 
given by Herodotua, and that extorted by the successes of 
Alexander, aa.given by Josephus. At the time of Cyrus, the 
island (/ Cyprus was included in the province of Coelesyria ; 
but in the time of Ptolemy, was separated from it. In the first 
instance, the tribute paid was 350 talents *. In the latter in- 
sUnce, it was farmed to Eveigetee fur 8000 talents ; but if the 
taxes were farmed by a Jew, he was to pay double that amount, 
and,, moreover, supply to the royal treasury the mcmey required 
to redeem the confiscated goods of such persons as had not paid 
their taxes f. 

During the period of the Macedonian empire, the predous 
metals were spread in great abundance over the whole eastern 
shores of the Mediterranean ; and if there had not been a very 
large portion of them hoarded up in the royal treasury, th^ 
value must Have fallen much lower, in comparison with other 
commodities, than was actually the case %. 

The Romans. — The extension of the Roman emigre, until it 
comprehended almost the whole of the known world, if it tended 
to diminish the production of the predous metals, powaf uUy at- 
tracted them, from Aaa and Africa, to its own metropolis. It 
is thus that the enormous fm-tuoes of individuals, which are re- 
lated by historians, are not to be accounted for. The descrip- 
tions of such fortunes, it is true, are niri confined to their mere 
metallic wealth, but mclude their lands, houses, slaves, and fur- 
niture, and also money lent at interest on mortgages or othft

prodi^ua degree, tliat remarkable nee in the prices of other 
commodities could not have been espenenced/vhich is noticed 
by all writers. As, among other instances, we know that the 
hoHse of Marhis *, at Misenutn, was purdiased by Cornelia fm 
75,000 drachmas "f-, and a few years after sold to Luctillus for 
SOO,SOO drachmas J. The fortunes of private individuals itiay 
be judged of by a few select notices to be found in contemporary 
autbors. Crassus is said to have possessed, in lands, bismillies §,

This result does not agree precisely with that of any other 
mineral, with respect to the component parts, but it apjmMicfaes, 
in some measure, to atiorthite, a spedes of felspar disoovered by 
O. Rose. Anorthite is entirely decomposed by concentrated mu- 
riatic add. It likewise contains a considerable qiiantily of mag- 
neffla, but what particularly deserves notice is, that no other fos- 
sil containing much magnesia gelatinizes with acid. The quan< 
tity of silica and Ume in that part (^ basidt which gelatinizes 
with atnds, agrees completely with that contained in anor- 
thite. But, on the other hand, anorthite contains a far greater 
quantity of aluminous earth, considerably less magnesia, and no 
alkali. On the whole, it appears that that part of basalt which 
gelatinizes with acids, is the regular mass from which the vari- 
ous crystals are developed, that occur so frequently in basalt. 
For example, if is easy to perceive, that in cqnsequenoe of the 
disappearance of magnesia, Labrad<H- felspar, that universal com- 
ponent part of dolerite and syenite, as well as of many meteoric 
stones, stilbit so frequent in basalt, as well as chabasie, prehnite 
and arragonite, will be found in the niass. 

The portion whit^ does not gelatinize, has nearly the same 
component parts as augite -

The quantity of alkali is remarkable, and it might be sup- 
posed that it was acquired in consequence of the silica in the ge- 
latinizing portion being separated from that which did not gela- 
tinize by Uie carbonate of potash ; but that cannot be the case, 
because the powder was first of all acted upon by diluted muzia- 
tic add, and then carefully washed. 

The result of the investigation of the decomposed mass was, 
that the quantity of silica, titanium, lime, magneua, and the al- 
kalis was diminished, while that of the oxide of iron was ctm- 
dderably increased.

On the Chimera Jnimalcule. 

Ii: is a very generally diffused opinion, although suppcnted by 
no poative facts, that those animated creatures belonging to the 
lowest classes to which, on account of their minuteness, the 
name of Microscope Animalcules has been given, are formed by 
the simple aggregation of the so-called orgiuiic molecules ; and 
Dr Hermann has endeavtmred to explain the OHitagious nature 
of chcJera upon this supposition. As umilar views have been 
more than once suggested, and it is to be feared that their plau- 
sbility may gain for them a more extended credence; the o|h- 
nioQ of a naturalist deeply versed in microscopic inquiries, and 
who has personally observed the oriental plague, a disease not 
^similar in some of its characters to cholera, merits conuder^ 
tioD. Professor Ehrenberg, in a late furtive jnece, has express- 
ed himself in the following terms upon this subject. 

To the doctrine of the umilaritj of the contagion of plague 
and of cholera, is connected with another wbich has lately found 
its way into the public journals, and which is merely a revival <^ 
the old and antiquated idea of small invisible insects which ge- 
nerate this contagion by thar irritatiim, poison, &c., and propa- 
gate it by their increase and migrations. Similar stories are to 
be found in the traditi<Mi8 of various people as well as those of 
the poisonous look of some human faces, of the dragon, c^ 
witches, magicians, the second sight, &c., formerly so seriously 
believed, but now only tbou^t ridiculous. Linn^, the great 
rrfonna- of natural histOTy, first took this fabulous animalcule 
into the domain of natural history, pr<^bly anlj widi the 
view of directing the attention of naturalists to the suljecL

166 On theChdera JtUmalaile. 

It was Baid to be the csuee of the pestilential blisters of the 
Gulf of Bothnia. He gave it the Termiform shape, and the 
yellow colour of northern tradition, and conferred on it the 
scientific name, more ndicuknis than formidable, of the Infernal 
Vurj {Furia infentdHs). Before diat, at the time of the plague 
at MarseilteB in 1731, the contagion had been ascribed to small 
infusory'like winged or mitelike, yet invisible, animals ; and at 
the time there appeared in the French language many treatises, 
which must now appear absurd to every well-informed per- 
son. One of these, printed anonymously in 1726, to push the 
matter still farther, deduces all diseases from these animalcules, 
which are designated by the fc^owing name : VerM agtovpiaians, 
court de ventritteSf barbon qu^umt, douifiang, erect^, jiitu- 
lairet lacrymaar,_fleuistes iflancs! The traditicm of the Lin- 
nean Furia still remains in Finland, where the anthrax is oom- 
tnon ; and, in Siberia, I found, in 18S9, on my journey with 
BartHi von Humboldt, a ramilar tradition regarding the cause of 
the Siberian pestilential boil, only that it was ascribed to flying 
ita^ insects, without, however, one of them ever having been 
esacUy characterised or even taken. Although we passed 
through many places infested with the pest, and I neglected no 
opportunity of learning the causes of the disease, I found no 
trace of this insect 

. A nmilftr tradition gave rise to the questiim which was put 
to Dr Hemi»ich and myself, in the year 18S3, by the Pacha o£ 
Egypt, whether it was true that, in Dongala, there were flying 
teorjnons which produced mortal wounds, for the troops refused 
to march there, having already sufiered much from those with- 
out wings. As during my natural history researches for nine 
months in Dongola, I had found nothing which justified this 
bdief, except the troublesome small mosquitoes, which were 
Deither p«»sonous, nor scorjHons, the mind c^ the Pacha was set 
at ease. 

As was to be expected, the same idea of invinble poisonous 
insects was transferred to the contagion of cholera ; yet it is 
hardly credible that Hahnemann, as stated in the Xi^pzic Jour- 
nal, should have for this reastm recommended the sedative ef- 
fects of camphor, because it killed these insects, and so es< 
pelled the cholera.

I have, rtH" many years, made these minutefit of orgamc bo- 
dies the subject of my particuiar inquiries, aud have for th^t 
purpose employed the best instrumeuts. But none before me, 
nor have I myself, ever succeeded in finding in the air these 
small bodies to which tradition had given a real existence. I 
must, therefore, warn medical men from modes of treatment of 
cholera founded upon this principle, for no naturalist has yet 
observed these animalcules. I have never observed these ani' 
malcules under the microscope, at the time of the plague in 
Egypt and Sib^ia ; and previous to my African journey, in the 
Hospital of the Charite at Berlin, I had examined with the mi- 
croscope many contagious cutaneous eruptions, iritbout having 
ever seen them. While, by the most rigorous microscopic ac^ 
curacy, I have made the angular discovery, that infusory ani- 
malcules, from |th to D^egtb of a line in size, possess an orga- 
nization similar to many of the higher animsls, and have de- 
monstrated their propagaUoa by eggs and internal organs 
which are leas than jgioi^th of a line, or irsVaa^'i '^ ^'^ i^uJi 
in diameter, and are yet disUnctly visible. 

What must, then, be the size of the pest or cholera animal- 
cules, or cours de venlrietes, if they were not discernible by 
such instruments .■' The (pinion is to be classed in the same ru- 
bric with the traditions and hypotheses of dragons, &c., and has

According to the observations of Professor Ehrenberg, the 
so called " Priestley^s Matter,^ when it is not formed by real 
animals of a very different form, was by algas ; and particularly 
when it appears as a pellicle or cuticle, is the result of putrefac-

On the CrystaMization of Ice, and of Vdns of Ice in Ice. By 
Professor Hessel. 

r o& some time past I have been occupied with observations oa 
the difierent forms of crystallization. The crystalHzation of 
water under certun condition^ induced by artifidal means, 
formed also the subject of my inquiries. I shall here briefly 
detail one of my experiments, which I have repeated frequently 
of late, as I reckon it not unimportant for the doctrine of veins, 
whose different modes c^ origin can, in my opinion, only be sa- 
tiefuctonly expltuned by collecting as many examples as posfflhle 
of the formation of veins and vein-like masses since the commence- 
ment of historical epochs. So that we have then only to inquire 
whether this or the other vein, or assemblage of veins, bears most 
resemblance to lava-vdns in lava, to veins which may be gihi- 
odered as canals filled up by mineral springs of some sort or 
other, to fissures filled by subfimations, to fissures which have 
been the outlets for alternate streams of fluid or elastic matters, 
and which have been gradually closed by the deporation of solid 
matters, or to fissures which have been filled by infiltration from 
above,. &c. ; or whether these veins are to be viejved as the result 
of the contemporaneous congelation (crystallization) of two or 
more heterogeneous masses, one of which has filled fissures in 
the other, but which have never been in reality open. 

Upon this supposition every experiment on the ori^n of vein- 
bke mas^, however insignificant it may appear, nmst be con- 
odered as an augmentation of our resources for the elucidation 
of the origin of those veins which have not been observed by 
man, so that this communication is of interest not merely to the 
crystallographer hut also to the geognost. 

I set aside, in a warm room, a mixture of fine cUy and wata-, 
in which the latter was scmiewhat in excess, so that the thin mud 
could be easily stirred about with a fine hair-brush. Upon 
resting for some time it divided into two portions, the under- 
most of which connsted of moist clay, and the upper and least 
Gon^derable of clear water. During the cold days which we 
had in December (5° — 10° F.), I exposed the mixture aBer

take place till the mass hod returned to the state of re«t, but 
before the separation took piece between the clay and the water. 
The gtnicture of the frozen mass vaiied in different experi- 
ments. In every case, however, frozen mud and frozen clear 
water could be distinguished from eadi other. But the tatter 
did not occur as a stratum at die upper J)art of the mass, but 
was distributed through the substance of the frozen mud, 

1. The most common appearaoce was like that of sm^l 
quartz veins traverdng in different directioos a siliceous slate. 
The same as in hand specimens of siliceous slate, when two of 
the quartz veins meet one another, they traverse one another, 
slnft one uiother, or mutually cut each other off, Sec. was otv 
served distinctly in the present instance. The principle that 
the travernng vein is newer than the one traversed, could not be 
easily demonstrated to be correct in these ice vrins in the frozen 
mud ; nor could the idea of the contemponuteous formation of 
v^ns with the surrounding rock be admitted as unconditionally 
correct In these ice veins there was apparently a real cutting 
across cS one vein by another, so that the traversed vein be- 
yond the traversing pursued its original course, or was diverted 
somewhat from its portion, but more fi^uently one was com- 
pletely cut off by the other. Often we cmild suppose a true 
wed^ng out of such a van without a previously existing empty 
lissure [ffomoting its formation. 

S. Often the water-ice was distributed through the frozen 
' mud Uke the quartz in the fdspar of grap^ granite. The 
surface formed by cutting and polishing exhilnUng, like the 
latter Hebriuc, Arabic, and Chinese characters ; and these were 
still more characterised on die dark surface of the mud, than the 
greyish-white quartz on the whitish felspar. 

S. Another mode of distribution of the water-ice in the frozen 
mud, was its forming vertical plates, which were so grouped 
that the surface of the mass of mud on its middle section, re> 
gembled a concentrically radiated crystalline mass, the rays di- 
verging from the centre outwards. Several of these groups of 
rays were observed. Each ray projected to a coouderable height 
above the surface of the mud. 

During the formation of the veins, I sometimes observed also 
that of hollow spaces. These were endowd by three or more

quarters of an va/Sd, and were quite empty of the froEOi mud. ' 
The frozen mud, separated as much aa possible from tbe 
tnmspareni ice, gave, when thawed, a mtrist mud, so that crys- 
tallisation had {Hoduced no more ctunplete separatioD than sim- 
ple rest ; but die ordinary separation of the water fnxu the mud 
was produced in a much shorter time than by the mere (^ra- 
tion of specific gravity in the mechanical mixture. 

With regard to the causes of the three different appearances 
that I have enumerated, they appear to me to depend upon 
differences in the excess of water in the mud, on the tempera:. 
ture of the mass before it is exposed to congelation (sometimes 

bmlpg water was used), and especially the rajMdity of tbe an- 

geUtioD. Farther I can give no explanation.

{Tetrao UrogaBui) to the Forttt ofBraemar, By Jahes

The almost recent extinction in Britain of the largest European 
bird of the gallinaceous order, is a remarkable fact in the geo- 
graphical hbtory of the species. Its rein trod uction is also a 
circumstance of sufficient interest to deserve a det^ed record. 

The wood-grouse or capercailzie, was formerly a well-knowa 
and frequent inhabitant of the Scottish forests. It still occurs 
in con»deraUe abundance among the wooded and alpine dis- 
tricts of Europe, especially in Scandinavia. It is rare in France, 
well-knowD in (Jermany, not unfrequent in Switzerland. It 
spreads through Rus^ into Siberia, and is very numerous in 
several distticts of the north of Asia. It seems always to prefer 
mountmnous forests, and is rarely met with in pliuns or flat 
countries, however richly wooded. Its favourite trees are pines, 
Inrcb, and juniper. It feeds on the fruit of tbe last-named 
plant, and on the buds and tender sprays of the two former.

amined, to contain a spedes of beny ramilar to the cranberry,

These turds ate of polygamous habits, and consequently do 
not pair. During the breeding season, which commfnoes as 
aooD as the buds begin to expand, and continues throughqut 
the rajNd northern spring till the forests are clothed in their 
fxea^iest green, the male is frequently seen perched on some tall 
{une, where he moves })acl(wards and forwards, ultecing at the 
same time a peculiar cry, which seems to attract the neighbour- 
ing females. His head, on these occasions, is red and swollen ; 
his wings dependent, and his neck extended^ His cry is said to 
commence with a loud explosion, which is followed by a ncnse 
Uke that t£ the whetting of a scythe. This is hetu^ at .a great 
diaUUQce, and, as soon as the females are collected aroand the

The last capercailzie recorded to hare been killed in Scotland* 
was ^ot, about fifty years ago, near Inverness. For a cona- 
derable time anterior to that period, it had been of extremely 
rare occurrence, and, although a solitary remnant of the ancient 
stock may have contrived to tnaintain a precarious existence for 
a few succeeding years in some obscure recess of the umbrageous 
forests of Braemar or Rothiemurchtis, it can scarcely be doubted 
that the species, ere long, ceased to exist as indigenous to Bri- 
tmn. tt was known to have been extirpated from Ireland at a 
considerably earlier period. 

When we consider the great size and beauty of this species of 
game, and its value as an article of food, we need not wonder 
that various attempts liave been made to naturalize it for the 
Second time in Scotland. I shall confine my present notice to 
the individuals which I have myself had an opportunity of ob- 
swving. ,

l&S Mr Wilson on the Introduction (f 

I had laBt summer the {dessure of sccompaajing my aoen- 
x&a friends, Professor Graham and Dr Greville, on a botaotcal 
excnmon to the Valley of Clova. The discovery of Astragaba 
aipimu, till then unknown as a British plant, and of other 
interesting rarities, rewarded their zeal, and baa been elsewhere 
recorded*, for myself, I chieBy plied the angler's trade, and 
had the satisfaction of providing my friends and their followers 
(Professor Graham being accompanied by a detachment of his 
class) occafQonally with an agreeable addition to their dinner in 
r^ioos where there were very few loaves, and (hut for my ex- 
ertions) no fishes. We afterwards crossed tlie Grampians, skirt- 
ing the " dark Loch-na-gar" and other fine mountain masses of 
that neighbourhood, and, descending tothe banks of the Dee, 
took up our residence for a time at the Casdetown of Braemar. 
I was wading down the Dee one fine afternoon, a little below 
Mar Lodge, and with a tighter pannier than usual, when I 
beard the cry of a bird to which I was unaccustomed, and my 
bad success in that day's angling induced me the more readily 
to diverge from the " pure element of waters,? tp ascertain what 
this might be. I made my way through the overhanging wood 
for a few hundred yards, and soon af^r reaching the road, 
which runs parallel with the river on its n^t side, I observed a 
wooden palisade, or enclosure, on the sloping bank above me. 
On reaching it, I found it so closely boarded up, that I had for 
a time some difficulty in descrying any inmates, but my eye soon 
fell upon a magnificent bird, which at first, from its bold and 
almost fierce expression of countenance, I took rather for some 
great bird of prey than for a capercailzie. A few seconds, how- 
ever, satisfied me, that it was, what I had never before seen, a 
fine living example of that noble bird. I now sought the com- 
pany of Mr Donald Mackenzie, Lord Fyfe's gamekeeper, the 
occupant of the neighbouring cottage. He unlocked the door 
of the fortress, and introduced me to a more familiar acquaint- 
ance with its feathered inhabitants. These I found to conust 
of two fine capercailzie cocks and one hen, and the latter, I was 
delighted to perceive, accompanied by a thriving family c£ young 
birds, active and beautiful. I made various inquiries on the 
spot ; but the fatigues of angling, and of entomolt^sing com-

biaed, prevented my writing down the result at the time, al- 
though I have Btill a distinct recollection of the leading focti*. 

It was, however, with great pleasure that I availed myself, at 
an after period, of Sir Thomas Dick Lauder's obliging ofifet to 
convey a series of queries to Mr Gumming, Allanquoich, Brae- 
mar. Lord Fyfe's factor, from whom I received the substance of 
the following information. 

The first importation of these capercailzies arrived from Sve- 
den about the end of the year 1827, or early in January 18S8. 
It consisted of a cock and hen, but the hen unfortunatdy died 
after reaching Montrose Bay. As the male bird alone arrived 
at Braemar, the experiment was judiciously tried of putting a 
common bam-door fowl into his apartment 'during the spring 
and summer of I82S. The result was, that she laid several 
eggs, which were placed under other hens, but from these eggs 
only a ^ngle bird was hatched, and when it was first observed 
it was found lying dead. It was, however an evident mule, or 
hybrid, and shewed such unequivocal marks of the cap^cailzie 
character as could not be mistaken. 

The second importation likewise condsted of a cock and hen, 
and arrived safely in this country in January or February 18S9* 
The female began to lay in the ensuing April, and laying in ge- 
neral an ^g every alternate day, she eventually deposited about 
a couple of dozen. She shewed, however, so strong a disposi- 
tion to break and eat them, that she required to be narrowly 
watched at the time of laying, for the purpose of having them 
removed, for otherwise she would have dertroyed the whole. In 

' During our excuraiou we generallj pasied over tha ground more rapidl; 
than was consisteat with entomological oitBervatiou. The objecta sought for 
b; the botanist are generally of larger uze, and Iwing alHO loyers of light and 
sunshine, thsj are more easilj distinguiahed tlian moat of the Inaect tribes, so 
many of which court concealment and the riiade. I was, however, fortunate 
tn obtaining near the Spittal of Glenmuick the scarce heath-buttea^j Hippar* 
elUa Tpphon, which I had never before seen alive in Scotland j and in open 
glassy glades, amongthewoodswhlch^cirt the right bank of the Dee, between 
Abergeldy and Invercauld, I captured the rare «nd beautiful HipparMa 
Bkm^tia, commonly called the Scotch Argus, a apedes hitherto fbund chiefly 
in the islaud of Anan, and not prerioualy known to occur so far north on the 
mainland. Of the rarer Diptera, Pediaa ricMa may be mentioned as not un. 
frequent among the woods of Braemar.

164 Mr Wilson on the Introduction of 

fact she did succeed in breaking most of them, but eight were 
obtained uninjured. These were set under a goiudioo h^o, but 
only one biid was hatched, and it died soon after. lot the spring 
of 1830, the'hen caperculzie laid eight eggs. Of these she broke 
only one, and, settling in a motherly maoner on the other aevea, 
she sat steadily foe five weeks. On examining the ^;gs, howevea', 
they were all found to be addle. " It is to be remarked," Mr 
Cumming here observes, " that in 1829 and 1830 th? hen had 
access only to the cock that was brought home with herself." 

In the early part of 1831 , three apartments were ingeniously 
formed adjoining one another. The heo was pUced in the 
central chamber, between which and the enclosure on either 
side, each of which contiuned a male, there was an easy com- 
munication^ so contrived, however, that the female could have 
access to both the males, whilst they, from their greater size, 
could neither approach each other, nor disturb the female as 
long as she chose to remun in her own apartment. In May 
and June of that year she laid twelve eggs, seven of which were 
set under a common hen. Of these, four were hatched in an 
apparently healthy state, one was addle, and the other two con- 
tained dead birds. Of those left with the capercailzie hen, she 
broke one, and sat upon the other four, of which two were 
hatched, and the other two were found to contun dead birds. 
Of the two hatched one soon died. Both the ham-door hea 
and the female capercailzie sat twenty-nine days, fnHD the time 
the laying was completed till the young were hatched ; and Mr 
Cummmg calls my attention to the fact, that there were birds 
in all the e^s of this year's laying except one. 

My visit to Braemar took place about the first week of last 
August. I think all the five young were then alive, and al- 
though only a few weeks old, they were by that time larger 
than the largest moOT-game. I had no opportunity of handling 
them, or of examining them very minutely, hut the general view 
which I had of them, at the distance of a few feet, did not 
enable me to distinguish the difference between the young males 
and females. They seemed predsely the same at that time 
both in size and plumage, although I doubt not* the male 
markings must have soon diewn themselves on the young cocks. 
The ungle surviving bird of those hatched by the mother died

of an accident, after living in a very healthy state for sereral 
wfeeks. Two of those hatched by the common hen died of some 
disease, the nature of which is not known, after lingering for a 
considerable time. It follows that there are only two young 
birds remaining. These are both females, and when I last 
beard of them some months ago, were in a thiiving condition. 

The whole progeny were fed at first, and for some time, with 
young ants, — that is, with those whitish grain-shaped bodies, 
which are the larvie and crysalids in their cocoons of these in- 
dustrious creatures, though commonly colled ant's eggs. At 
that period they were also occasionally supplied with some ten- 
der grass cut very short. As Boon as they had acquired some 
Strength, they began to eat oats and pot barley, together with 
grass and the various kinds of moss. They are now fed like 
the three old birds, chiefly on grain and heather tops, with the 
young shoots, and other tender portions of the Scotch fir. I am 
informed that the distinction between the sexes had become very 
obvious before the death of the young males. The plumage of 
the latter was much darker, their general dimensions were great- 
er, their bills larger and more hooked. These characters be- 
came very apparent during Xoyemher and December. 

The old males have never yet had access to the young birds, " 
so that it has not been ascertained whether they entertain any 
natural regard for their offspring, or would manifest any enmity 
towards them. From the continued wildness of the old birds, 
espedally the males, it was found difficult to weigh them, with- 
out incurring the risk of injuring their plumage. However, the 
male which arrived in 1S29, and which then appeared to be a 
bird of the previous year, was lately weighed, and was found to 
be eleven pounds nine ounces avoirdupois. Judging from ap- 
pearances, it is believed that the weight of the old hen would not 
much exceed one half There is, indeed a striking disparity in 
the dimensions of the sexes in this species. 

I have not yet heard the result of this season's courtship. The 
intentJCHi is, as soon as some healthy broods have been reared in 
confinement, to liberate a few in the old pine woods of Braemar, 
and thus eventually to stock with the finest of feathered game 
the noblest of Scottish forests.

This species is nearly allied to ^.mummiita, which flowered in the Botanic 
Garden lately, and is figured in BoL Mag. t. 3093., but is easily distin* 
guisbed by the character given above. They undoubtedly belong to the 
same eenus, but whether they should be left as species at Arbvius, or re. 
moved to G^iaUberia or Arelotlaphj/ht, or erected into a new genus, must 
be chiefly regulated by the fruit, which I have not seen. I doubt whe- 
ther the calyx, though persisting, will become berried as in Guo/fAnio, 
but the anthers are, as in that genus, provided with 4 awna. The pre- 
sent species is a native of Mexico, and was raised by Mr Neill from seed 
received fi-om Mr Don. From Mr Nrall we received it at the Botanic 
Garden. In both establishments it flowered during May, and is per- 
fectly hardy.

likewise by the Rev. Mr Craig, in January 1831. It flowered for the

at Comely-bank, near Edinbuivh, and communicated to Sir Neitl's gar- 
den at Canonmills. In both these establishments it flowered in May 
1832. I have no doubt of this being the spedes of Cavanllles, and veiy - 
little about Its being that of Jussieu, though the petals are figured (not 
described) by Cavamlles as acute, and though the flowers are said by 
Jussieu to be without pedicels In his plant. The leaves correspond with 
Cavanilles', and the station is the same. His figure represents tbe 
fiowera as secund, and a dried specimen brought home by Mr Anderson, 
and given to Mr James Macuab, has tht! same appearaoce.

This Is a very handsome Tariety, but I can perceive no good character by 
which it can be s]>ecifically distinguished. It is very robust, the leaves 
being much longer and narrower than in the usual form of the species, 
and very ollen with 6 folioles, the terminal one only, as in the common 
variety, being supported upon an elongated petiole. The flowers are in 
a dense raceme, and of a deep rich lilac, with two green striated spots 
on the veiiUum. It was raised from seeds sent to the Botanic Garden, 
Edinburgh, fi^m New Holland, by Mr Fraser in 1827, and flowered in 
tbe greenbouse for tbe first time in April 1832.

Kocky Mountains. It first flowered in November 1831, but much more 
abundantly in May 1832. 

If Sir James Smith had seen the living plant, I think he would have ^ven 
a diflTerent specific character. The leaves, in the recent state, are de- 
cidedly tumid, both above and below, being depressed only along the 
middle rib on either aide.

in July 1820. and being kindlir sent by C<^(Hiel lindesay, irere receiTed 
at the Botanic Oarden, Edlnburgb, twelve motitlu afterwards. Several 
plants flowered freely in the greenhouse in May 1S33. They form a 
handsome addition to the speties previously in culUvaUon- There ia 
reason to believe'tliat the seeds will ripeu.

division having on tbe outside a lanceolate bractea. Flomers pedicellate, 
white. Calj/x S.phyllous ; phylla cordate, villous both within and with- 
out, but much more harshly without, somewhat reflected in their sides, and 
forming a prominent edge where they meet each other. Pelait pubescent, 
much smaller than tbe calyx segments, concave, gibbous at Uieir base, 
their sides fbrmed into two blunt parallel wines, which project towards 
the axis of tbe flower, apex extended into a blunt linear appendage, at 
first curved towards the axis, but afterwards bent back, and passing out 
between tbe segments of the calyx. Stamens 6 (perfect), immediately 
within the petals, and alternating with the segments of the calyx, shorter 
than the petals, and included within their folds, alternating on the same 
urceolate borderwich, and somewhat shorter than, ovato-lanceolate scales 
(abortive stamens), which are hairy on the outside, smooth within; fila- 
ments glabrous ; anthers short, bilocular, bursting along the sides. Pol. 
leii yellow, granules round. Sligmata cohering to each other, small, ca- 
pitate, colourless, shining. Slyle> 6, glabrous, in contact in the centre of 
the flower, scarcely longer than the stamens. Gertaen 5-lobed ; in its 
early stages lobes conical and a little rough, afterwards rounded, green, 
depressed in the centre, sod densely covered with stellate pubescence, 
S-locular, dissepiments from tbe edges of the valves, their two layers 
afterwards separating. Ovvlea two in each loculanient, with a central 
ridge of the valve between them, both attached to the central column 
below its middle. Pubescence every where on the plant stellate, except 
from abortion, when, as on the upper aut&co of the leaves, it often ap- 
pears single. 
This plant was received last year by Mr Neill at Canonmills, and in the 
Botanic Garden, £diabui^h, from Mr Knight on the King's Road; and 
both with Mr Neill and us, it flowered freely in the greenhouse in May 
last 1 am indebted to my acute friend Dr looker for many important 
. references r^arding this genus and Its allies, which led me to investi- 
gate its structure much'more closely than I otherwise would, and pre- 
vented my committing some nustakee.

This species is new in cultivation, and the flowers are larger than any in 
our gardens. I owe to the late Mr Fraser, colonial botanist, a native 
^edmen collected at King George's Sound, on the south coast of New 
Holland ; and. from seed picked off one sent at the same time to Mr 
Hacnab, the plant described was raised. It flowered in the greenhouse 
of tbe lioyal Botanic Garden in May, and will continue to l^ar flowera 
during the early part of June.

irregularly depressed over thuir surface, and each is raised on a sand-guM 
shaped portion of the disk, the upper lobe of which projects &om Its 
lower side a simple row of short dependent subulate hairs. 
The seeds of this pbnt were received at the Royal Botanic Garden, from 
DrFlscher, under the name adopted, in 1830, and flowered for the first 
time in May 1832. The profusion of lively coloured flowers in this spe- 
cies, which is less deformed by coarseness of herbage than others, makes 
it one of the most desirable for cultivatien.

SCIENTIFIC INTELLIGENCE. 

METEOBOLOGY. 

1. First View of Sierra Leone. — ^Dr Boyle, in his interesting 
wwk <Hi the medical topc^aphy of the western coast of Africa, 
says, " There are very few parts io the tropical world which at 
first sight hold out more allurements, even to the experienced 
traveller, than Sierra Leone. Its splendid scenery, and its beau- 
tiful river, together with its extensive, commodious, and general- 
ly secure harbour, and pleasant-looking town and villages, are 
calculated to excite the most flattering hopes in respect of health 
and enjoyment, notwithstanding strong previous impressions 
with regard to the contrary. On making Sierra I^one from the 
north, the mountains from which the peninsula was named first 
excite attention. They are lofty, perpetually clothed, from 
their summits to their bases, in all the fertile gaity of Nature^s 
verdant scenery ; and there is a pleasing and endless variety in 
the outline of iheir countless peaks and declivities. As the ship 
draws in with the shore, signs of cultivation appear, and increase 
with rapidity, both in number and attractiveness. Freetown, 
and the lately formed villages in its neighbourhood, at lirst ap- 
pear like anomalous patches in the view -, but on a nearer ap. 
proach, they add greatly to its beauty and its interest. When 
the ship has arrived just at that point of distance Irom which a 
person may see all the broad outlines and apparent characteris- 
tics of an extensive scene, without being able to discern the mi- 
nute details, the effect is magnificent. On the left hand is the 
BuUoon shore, low, but covered with luxurious and richly 
coloured bush, an occasional palm and pullom tree, rising in 
graceful form above the neighbouring mangroves : — in appear- 
ance it seems to embody the notions formed of fairy-land, hut 
its realities most sadly illustrate the folly of such dreams. Tbe 
middle ground also occurs on the left hand, and it gives a va- 
riety to the view. In front are the spacious river, extending 
farther than the eye can reach, and the north side of the penin- 
sula, with its lofty mountains, and Freetown, ruiming to the wa-

ter's edge, tmd sunnouDted by the barracks, and protected by a 
handsome fort, and a coast, forming small and conveniept bays, 
from the town to its termination at the Cape^ which runs boldly 
into the sea. On the ri^t is the Atlantic That a scene, com- 
posed of such ostensible material features, is grand and impos- 
ing, may readily be supposed ; but those who are ignorant of 
the peculiarities of a tropical climate, and its seductive influence 
on a stranger, can form no adequate notion of the character and 
extent of its actual power. For the moment home is forgotten ; 
or if remembered, the remembrance is accompanied with a de- 
ure it should be situated in such a seeming paradise. In thus 
q)eaking of the view on arriving at Sierra Leone, we are sup- 
posing the settlement to be made on a fine clear day, when the 
atmosphere is bright and comparativdy devoid of malaria, and 
the river runs its natural course, unswollen, aod free from dis' 
oiloration. Should the arrival, however, happen at a di&rent 
period, when the atmosphere is dense, oppressive, and fraught 
with deleterious e^ihalalions, and the rains are deln^g the face 
of the country, and at once augmenting the river, and destroy- 
ing its beauty, then Sierra Leone jwcsents a very di^rent ap- 
pearance ; there is nothing to excite a pleasing anticipation, but 
there is a world of causes for apprehension and for dread. The 
realities of the scene are, of course, unaltered, for the t?ra periods 
are the property of the climate, and must be alike endured by 
the colonists; but the appearances present a melancholy and 
fearful contrast." 

2. Description o/* an African Tomado.-~-T\ie seaaons at 
Sierra Leone are divided into the wet and the dry. The latter 
is generally ushered in by the exploaon of two or three torna- 
dos, which, although formidable in themselves, are still so long 
connected with the approach of a pleasant time, as that the in- 
habitants have sometimes prayed for their appearance. One erf" 
those strange commotions of nature is thus described by Mr 
Boyle:—'* A violent tornado appears to strangers a most ap- 
paling viritation, and produces an extraordinary effect Upon 
their feelings. It consists of successive flashes of the most vivid 
lightning, tremendous shocks of thunder, rapidly and alarm- 
ingly rriterated, impetuous gusts of wind, deluging rain. Thfs 
terrific combination of the elements sweeps aloi^ the whc4e of

the coast under conaidenition ; but it ocxurs with pecuHar force 
on what k called tbe windward coast, especially at Sierra Leone. 
lis denomination is derived from the Portugese, it being a oot' 
ruption of tb« word tnieno, which means tbundar-storm. Its 
approach is first dtaccmUile by the appeoranoe of a small dear 
silvery speck, at a hi^ altitude in tbe heavoily expanse, whidi 
increases and descends towards tbe bonzon, with a gradual and 
slow, but visible motion. In its descent it becomes circumscribed 
by a daric ring, which extends itself on every aide, and as soon 
as tbe silvery cloud approaches the horizon, v^s it in impene- 
tr^e gloom. At the moraent the elements seem to have cewed 
Aeir operations, and tbe very functions of nature to be para- 
lysed ; the atmosphere appears to be deprived of the spirit of 
ritaltly, and a seniation of approaching sufibcation pervade* 
■od oppcesses the physical system. The mind is wrapped in 
awe and suspense, but tbe latter is speedily rdieved by tbe dark 
horizon being suddenly illuminated by one broad blaze of elec 
trie fluid; pesis oC distant thunder then break upon tbe ear, 
and rapidly a|:^roacb, and increase in fervency and violence, till 
the shocks become appaling ; when the thunder is at its loud- 
est, a tremendous gust of wind rushes with incredible and often 
irresistible vehemence from the darkened part of the horizon, 
Dot rarely in its course carrying away roofs of houses and chim- 
ney-tops, blowing down or uprooting trees, and laying the stout- 
est and largest ships on their beam-ends, or sinking them under 
weigh or at anchor; and to that succeeds a furious deluge of 
nun, which falls in one vast sheet, rather than in drops, and 
ocmcludee this terrible convulsion. The lightning is of the most 
vivid descrifriJon, and, contrary to what has been reported of it, 
gddom sheet-lightning, but forked and piercing, and oflen ex- 
tremely destructive, both to things animate and inanimate. Its 
apparently doubtful, wild course, is sometimes directed to a large 
and k^ty tree, and the foliage, at the points of contact, is bUsted 
on tbe instant, tbe exposed branches are severed from the trunk, 
and i»obab]y tbe enormous trunk itself is rent to its basis and 
destroyed. When it comes in contact witb a house, it fre. 
qoently leaves it as great a wreck as ships have been seen to be 
oil coming out of a severe action, ch* after a destructive storm ; 
and, occasiooajly, the building entered by it may happen to re-

Occadonally the spindle of a ship's mast, the most elevat«d'f))M 
of it, may appear to' be the point of attraction, and it will flodie^ 
tjmes dart among the spars and cordage harmtess, descmdiiig 
till it reach the deck, when it suddenly quits the -vessel by hosh 
aperture, and rapidly returning through another, seems'to have 
acquired a new character with incredible -velocity ; tor,- eteerih^ 
its strange and rapid course into the meindeck or hotd, it wiU 
kill, maim, or injure every animate or inanimate w^h nhich'it 
comes in contact. Much good has unquestionably been eflected 
by conductors; but those who have watched the progress of 
the electric fluid, will hold the theorist in no estimation, ^vho 
does not make the atmosphere the first and most important point 
of consideration. The heavy peals, or rather the terrifying 
shocks, of thunder which follow the lightning, irequently not 
only shake the buildings at Freetown, but the very foundations 
on which they stand ; and the reverberations from the surrdtmd- 
ing mountains increase, if possible, the awe excited by elemert- 
tary commotion. The succeeding rain, or rather deluge, is 
happily of short duration, and rushing down the various inlets 
and indentations in the adjoining mount^ns, it forms into streams 
even a few minutes after its commencement, which sweeps 
through the streets of Freetown with astonishing velocity, bear- 
ing with them all the exposed vegetable and other matter, fn a 
state of putridity or decay. Such is the tornado, and it is%y 
the preponderating power of its gusts, and the atmospheric in- 
fluence of lightning and its rains, that noxious exhahttions frdth 
the earth, and deleterious miasmata, before confined to' 'the 
neighbourhood of their origin by opposed or light ctrireftfs faf

' 3. On fA^ Stance to ruTmh Spray of the Sea may be carried. 
— -A few remarks on the distance to which spray from tbe sea 
is sometimes carried inland by storms o? wind, may not, per- 
hapst be deemed altogether irrelevant to the subject we are 
treating upon. Sea-water is brought into tbe immediate ndgh- 
bourbood of Manchester, which is at least thirty miles from the 
nearest coast, by every violent and long conUnued gale from the 
we&t; and the exact proportion in given quantities of rain-water, 
collected on several occasions of this kind, has been determined 
chemically. That the sea is tbe principal source whence the 
■alt is derived, witb which the rain that falls in this town and 
its vicinity is occasionally impregnated, cannot, I think, be 
doubted; as I have clearly ascertained, by direct experiment, 
that its excess or deficiency depends entirely on tbe direction, 
toKe, and duration <tf the wind. Rain collected in clean glas»- 
vessels, a few miles to the north of Manchester, when the wind 
Uows moderately from the north or north-east, scarcely ever 
exhibits tbe slightest trace of muriatic acid, on the application 
of the most delicate test (nitrate of silver), even when reduced 
two-thirds ur three-fourths by spontaneous evaporation ; though 
aamjples collected in the town, precisely at tbe same lime, on be- 
ing subjected to tbe test, generally have their transparency 
awre or less impaired. This fact seems to prove, that, notwith- 
standing muriate of soda is never raised into the atmosphere by 
evaporation, yet tbe sir over large towns usually contains a very 
minute portion of muriatic acid, which, as Mr Dalton observes, 
is probably supplied by the sublimation of muriate of ammonia 
tduring the combustion of fuel. A considerably increase of mu-

nntic acid takes place in the r^ wlucli fallg ic Manchester, 
^en Kcompanwd with a brisk breeze from the west, of Beveral 
boiin' tbira^n ; as is evid«it tram the graater degree of op^- 
ty obserred in «HD^es caught under such ciFcuaistances, when 
treated wiUi a few drops of the solution of utrate of alver ; aod 
that which &11b in the adjacent oountry, then manifests a sena- 
Ue trace also. Indeed, the direction of the wind remiuniag the 
Mine, its fi»ce and duration aeem atmost entirely to regulate the 
qaantity of muriatic acid ia the atmosphere; which oompletely 
establishes the fiu:t ^t it is brought from the sea by the me- 
chanical action of powerful currents of ^r. The utmost dis- 
tance to whi^ sea-water is conveyed by tempestuous trinds is 
Bot easily determined. Sir H. I^svy, in his £Iem«it8 of A^- 
cultund Chemistry, p. S95, states, that " in great stcrros the 
spray of tile sea has been carried more than fifty miles from the 
shore ;^ but he does not give hb authority. Being at Blackv^, 
m Derbyshire, the residence of my relative John Bladtwall, 
Esq. on the 9M of November 1814, when a violent hurritsne 
•ecurred, whidi did extenuve damage on the southern coast, I 
took several opportunities of examining the rain which fell at 
intervals on that occasioD, and unif(»inly found that it became 
extremely turbid on application of the test, evidently coutainii^ 
tnuch more muriaiic acid thau nun collected in large towoa, 
duriag cdm weather, is ever found to contain. The etooR 
eomraenced on tbe^night of the 22d of November, and conti^ 
nued, with little abatemeitf, till after noon on the SSd. The 
wind Mew from the south all the time, and the place of ob«er> 
vaUon is 140 or 150 miles from the eea in that direction. This 
U, peiliaps, the greatest distance oa ^eoord to which sea-water 
bas been dearly ascertamed to be conveyed by the wiod ; and 
Aat it extended much further is lu^ly (Mnobable.— J/anciedMr

while the herds could enjoy the warmth oi the sun, and snuff 
the breeze that Sflreeps so freely over theta; in the winter, the 
rich cane on the ri^er banks, which is an evergreen, would fuTt 
nish faod,-n-while the low grounds, thickly covered with tol^ 
and forest, would afford protection from the bleak winds. I 
know few subjects more interesting than the migration of wild 
animals, connecting, as it doea, the singular display of brute 
instiiut, with a wonderful exbibibon of the various supplies 
which nature has provided for the support of animal life, undei 
Ml endless variety of circumstances. These paths are Darrow* 
and ranarkably direct, shewing that the animals travelled in 
fungle file through the woods, and pursued the most direct 

ecmte to their places of destination.^ Deer are more abuo- 

(lant than at the first settlement of the country. They increase 
to a certain extent, with the population. The reason of this 
^ipears to be, that they find protection in the neighbourhood of 
mui, from the beasts of prey that aasajl them in the wilderness^ 
and from whose attacks, their young particularly can with dif- 
ficulty escape. They suffer most from the wolves, who huijt 
in packs like hounds, and who seldom give up the chase until a 
deer is -taken. We have often sat, on a moqniiglit summer 
va^X, M the door of a log-cabin on one of our prairies, and 
beard the wtdres in full chace of e deer, yelling very nearly id 
the same manner as a pack of hounds. Sometimes the cry would 
be heard at a great distance over the plain ; then it would die 
away, and again be distinguished at a nearer point, and in ai^ 
other dicection ;-— now the full cry would burst upon us from a 
nejghbonriilg thicket, aad we would almost hear the sobs of the 
(!XhaaBted,dser ;-^nd again it would be born away, and lost in 
tba dietsDce. We have passed nearly whole ni^ts in listening to

ZtDBQetiBe nmnbers of deer are killed every year by our hunters, 
irho take diem tin' thar hams and skius alone, throwing away 
the rest of the carcass. Venison hams and hides are important 
articles of export : the former are purchased ftom the hunters 
at S5 cents a pair, the latter at SO cents a pound. In our vit 
lages we purchase for our tables the saddle of veoisoa, with the 
bams attached, for 37^ cents, which would be something like 
1 cent a pound. — There are several ways of hunting deer, all 
t^ which are equally ample. Most generally the hunter pro- 
ceeds to the woods on horseback, in the day-time, selecting par- 
ticularly Certain hours, which are thought to be most favourable. 
It is said, that, during the season when the pastures are green, 
this animal rises from his lair predsely at the rising of the moon, 
whether in the day or night ; and I suppose the fact to be so, 
because euch is tiie testimony of experienced hunters. If it be 
true, it is certsinly a curious display of animal instinct. This 
fcour is therefore always kept in view by the huntert as he rides 
slowly through the forest, with his rifle on his shoulder, white 
Itls keen eye penetrates the snrrounding shades. On beholding 
a deer, the hunter slides from his horse, and, while the deer is 
observing the latter, creeps upon him, keeping the largest trees 
between himself and the object of pursuit, until he gets near 
enough to fire. An expert woodsman seldom fmis to hit his 
game. It is extremely dangerous to approach a wounded deer. 
Uniid and harmless as this animal is, at other times, be no 
sooner finds himself deprived of the power of flight, thaS he be- 
comes furious, and rushes upon his enemy, making 'desperate 
plunks with his sharp horns, and striking and(rATt(p]ihg''foM- 
ously with his fore-legs, which, being extremely muscular', and 
armed with sharp hoofd, 'are capable of inflicting 'vetf serine 
wounds. Aware bf this circumstance, the hunter ttppnMttbes 
Rim with caution, and eithftr secures h!« prey bytf webntbshdt, 
where the first hds been but partially Bucceasfii!, or, m 4s«cre 
ftequently the case,' causes his Sog to seize the wouiMed aniiilil,

in the neighbourhood of the saltJicks. These are- spota lAere 
the earth is impregnated vith saline portaclea, ornkere the wlft- 
water oozes through the soil. Beer and other grazing animlifa 
frequent such places, and remain for hoars Itelung thfr eoi^ 
The hunter secrets himsdf here, ather in the thick top of' ■ 
tree, or most generally in a eoreen erected' for the porpaae, aad 
artfully concealed, like a mask-batterf , with logs or greeb 
bou^s. This practice is pursued only in the sutniner, or ewly 
in the autumn, in doudless nights, wh«t the moon ihtnes bt^ 
liantly, and objects may be readily discovered. At the risitig 
of the moon, or shortly after, the deer having risen from their 
beds, apjHxwch the Hck. Such places are generally dennded of 
timber, but surrounded by it; and as the animal is aboat to 
emerge from the shade into the dear moon-tight, be stops, looks 
cautiously around, and mufis the air. Then he advances a few 
Steps, and stops again, smells the ground, or ruses his expanded 
Dostrits, as tf he "snuSed the approach of danger ta eveiy 
tainted breeze.^ The hunter sits motionlesE^ i^ tnott-lneath- 
less, waiting until the animal shall get within rifl&«hot, and 
until its position, in relation to die buDt«- and the light, shall 
be favourable, when he £res with an unerring aim. A few deer 
only can be thus taken in one night, and after a few nights 
these timorous animals are driven from the haunts which are 
thus disturb^. — Another practice b called driving, and is ooly 
practised in those parts of the country where this kind of game 
is scarce, uid where hunting is pursued as an amuaeoidiit. A 
large pi^y is made up, and ^ hunters ride fordfc with their 
dogs. The hunting ground is selectedi and, as it is prtUy n^ell

7. On the Gold, Siher, and Platina iif Russia.— The art- 
Husl [H<oduce of nlrer in the Runias, is estimated at ^ut 1000 
pouda, o( forty pounds each ; but what, after all, is this 1000 
pouds, er 40,000 pounds, to the produce of the Valendana tnJne' 
in Mexico, which ior manj long years produced its millions of 
dollars annually ? " Young Demidoff had not yet returned throat 
Italy ; from his relation and agent DaniloS*, I met with every 
attention. Hia cabinet contuned many beautiful specimens «rf 
platina, most of which were designed as presents to the crowned 
beads of Europe. Although some ^ngle masses of platina 
weighed seven or aght pounds, none could be cmnpared to 
those in the cabinet of the mining oorps, one of whidi wdghed 
about S7 pounds. My own specimens, which wire presented 
to me by Zobolefsky, altbou^ weighing 800 gr^ns each, and 
d which I had been not a little proi^d, dwindled away, in the 
view of tbo great varieties lying in profusion in Demidoff's ca< 
binet. Owner of the most celebrated platina depositi^. and gold* 
washings, he had had many opportunities, in the MfUrse of « 
few years, of selecting and putting aside not only Iqrge maonve 
lumps of gold and platina, but what wasi yet. more inter^tmg, 
a great variety of most beautiful aod perfect crytt^s of gold. 
The mass of platina before alluded to, as w^ghing ^ pounds, 
was found completely isolated, altid at nearly 60 versta from the 



19d Scientific IntdHgenee. — Afmerahgjf. 

usual deponid of ]^tina, in a bed of red ehij, where some staves 
were employed in making bricks. Those sl,reains in the beds 
and on the banks of which the gold deports are met with, con- 
tain more of gold, and lees platina, on the European than 
those on the Asiatic ade of the tJr^ Mountains. The amount 
of gold obtained from these washings, had amounted for the 
year 1830, to nearly half a million sterling. It may be well 
nnagtned to what an extent their operatiotis must be extended, 
when the 100 pouds, or 4000 pounds weight of soil, seldom 
yield above 6S grains of gold, and varies from 65 to 180 grdns, 
—which is there conadered rich, — to tlie 100 pouds. Never- 
theless, their mining operadons are conducted with such skill 
and success, as even. to obtun, of thit limited quantity, nearly 
the iriiole amount ; and that, too, with such little cost, as to have 
been, indeed, far beneftth my expectation. Of the simple ond 
yet beautiful processes m«de use of in the gcJd-washings of the 
Ural MoontMins, I shall speak hereafter, well convinced of the 
great utility and service which they would be of , if made known 
to the mining regioni of otiier countriea^ The Demidoffs, Da- 
^doffs, and many other Russian families, are acquiring princely 
revenues from the employment of their slaves in these gold- 
washings ; but it is not alone the gold, — the plaUna itself is ano- 
thw great source of their prosperity ; more especially since all 
the plalina is now coined at the imperial mint, and established 
as part of the curr^it txaa of the realm. The coins made of 
platina are beautiful ; those large pieces with the head of the 
Emperor «re the best, and show better the effect and polish 
which coins of this metal can take. Though many hundred 
pounds weight of platina are coined mcxithly, into pieces of 11 
and 22 rubles, they disappear rapidly from the drculation. 
They may be met with occasionally, and a few at a time, in the 
hands of the brokers. I consider their price much above the 
London price of malleable platina, which is at present about S5 
AMogt English per ounce : considering that the crude platina 
is the produce of the country, the Russian price for malleable 
platimi, wHch is lAout SSs., is too extravagant; and yet this 
does not arise from the expense of manufacturing, but from the 
east of the material itself, which is far higher than. the platina of 
South America. The cause of this is the monopoly and easy

ing, by his own exertions, from obscurity to emmence^ that age 
and that country have some dsims to commendation in whioh 
the fmve of genius can overcome the obstacles of birth and for- 
tune and elevate its possessor to the society of ^ the n^Mest and 
wisest of the land. 

WiLLiAU R«S€(« was bom on the 8th of March 17SS, m 
the Old BowUng-green Housey which still exists in Mount 
Pleasant *, and is well known to many peraons by the engra- 
ving from a dmvtng by Ausdu. His paNnts, in- hundbid but 
comfortable circumstances, were little able to advance his edu- 
cUioD ; yet anxious for his imjHnvement, at the age of six they 
sent him to a scbool, kept by a Mr Mardn, for the elementaty 
instructicm of children ; whence, in about two years, he was re- 
.moved to the seminary of Mr Sykes, at that time a oxiKderaUe 
private school in Liverpool. 

The instruction which young Roscoe here recdved was con- 
fined to English reading, writing, arithmetic, and the elements 
of geometry. At ibe age> of twelve years he left school, from 
which pefiod he may be said to have been, in a great measure, 
his own instructor, until about the age of sixteen, whffli he was 
articled as derk to Mr John Eyes, a respectable attorney in this 
town. During the four years that elapsed between his leaving 
school and entering Mr Eyee*s office, he ooeupied himself with 
desultory English reading, in cultivating some 6elds rented by 
fais fothef, raid in frequenting the ps^ting-room of a porcriafea 
manofaetory in the neigf^bourhood, where he amused himsetf 
mth painting on china.' 

At that period of his Me his' Eoglisb reading 8[q>earE to have 
been rather confined. His favourite afutbors were ^ak^teare, 
Shenstooe, the poemtr of Mrs Cathnime I^i^M, and the Spec- 
tator. Prom tbe IbrtOet ht imbibed a decided predUeotioii f« 
poetry, and his taste tor EngH^ composition was [nobably no- 
d^ed on the el^ant examples contained in the latter. It is 
curious to trace his attachment to botany and the 6ae arts tathia 
«at1y period. The phencnaena of vegetaticHi, and the cultiva- 
tion of plants, appear to bare made a deep in^resnon on his 
youthful mind ; and in the little cultivate of his fktIterV fields^

■nrangemeot (rf Sdtanonen, and the nqterb botaaioal .{)drii- 
catioa on the same beautiful order of plants. The eariy tattjs 
in paintmg china-ware seem also to have first iaapired Innvi^ 
a lore of the fine arts, and drew him on to cultivate hk taste in 
th^ arts of de«gn, in which he not oiily diipli^ed the kiumiedge 
of an intellig^t amateur, but such practical pnifioienc!y,uiiiigbt 
have led to emiafnce, had his genius not been dincteditftodtar 
channels, as several slight but spirited etduogB by hia hami, 
yet in existence, amply testiiy. 

The rudiments of Latin he acquired between the age at n>- 
teen and twenty, by his own unassisted efforts, thou^ at a later 
period he read several of the best Latin authors in company 
■with his friends the late William Clarke and Richard Lowndes, 
two young men of Liverpool, equally intent with himself on 
menta] improvement. 

I may here men^n, it was not until a comparatively lat<t 
period of his life, and, if I mistake not, after ^e publication (^ 
the Life of Lorenzo had ^ven him celebrity, that he began to 
study Greek, In a copy of Homer in possession of Ins Caniily, 
we find the following note : — " Finished the Odyssey the day I 
came to Allerton, 18th March 1799.— W. K." 

From his fifteenth to his twentietb year, he appears, from 
some memoranda which be has left, to have studied very assidu- 
ously during his leisure hours ; and he luckily found some a&> 
oodates, with congenial tastes and habits, of whose fnendahip he 
always ^Kike, to his latest hour, with afiectionate regard. 
Among those the most conspicuous were Mr Edward Rogers, 
Mr WilUsm Clarke, Mr Richard Lowndes, Mr William Keil. 
son, and Mr Francis Holden. To the latter, whose various a«- 
qairetnents and extraordinary talents were in after life the ft«. 
quent theme of Roscoe's enthusiastic encomiums, he was di^tosf 
ed tn attribute his first inclination to the study of modem Jaii- 
guages; and he bad pleasure in acknowledging, that it was by 
the adviee and encouragement of this young friend, that h? de- 
voted himself assiduoasly to die study of Italian. In his ac- 
quisidon of the elements of Frraoh and Italian, he does not 
seem to have had any other asoGtance than the advice and en-

oouiagement of youog Holden, "who, seeing the aptitude and iiN 
duetry of his friend, rtrenuoudy urged him to pursue tbe path 
which his own genius had opened to hia aspirations after literary 
disdnctjon. 

In fact, Ro«coe owed very little of his acquirements to any 
ihstnictor. What he drew from the conTersation of his early 
assooates, there is every reason to believe be amply repaid in 
kind ; and, with the ^gle exception of Buma, I do not know 
any *^ our dbdogiushed writers who is lets indebted to others 
for aBastance in the road to literary eminence than William 
RoscoE— <ertmnly few of them could with more truth exclaim, 
in the language of Pkemitu, when a suppliant to Ulysaes, — 

"AvTiiiiiiKrH flif"- 

During the time <^ his apfu'enticesbip, Mr Roscoe formed an 
agreement with his friends Clarke, Lowndes, and Holden, to 
meet early in the morning, before the hours of business, for the 
purpose of reading together some I^atin aqthor, and discours- 
ing on what they read. The example of these youthful stu- 
dents cannot be too earnestly inculcated on the rising generation 
of this place, while the success of one at least of them in tji^ 
fields of literature is a striking proof of what may be obtained 
by such appropriation of hours too often lust to mental improve- 
ment. While classic authors thus engaged his morning le^re, 
Roscoe continued earnestly to cultivate Italian literature. It 
would seem that, before his twentieth year, he had read, in the 
original, several of the Italian historians, and, at that time even, 
had set his mind on becoming the biographer of Lorefizo d^' 
Medici, the great patron of the early restorers of ancient leara- 

He had, from an early period of his life, felt the force of po&- 
tic inspiration, and had undoubtedly cultivated th^ Muses with 
high promise of brilliant success, ere he had attained his twen- 
tieth summer. A considerable number of hia eariy verses re- 
main, which breathe an ardent spirit of poetry. Some of these 
are addressed to a young lady of the same age, whose poetical 
genius had excited his warmest admiration, and wl}0 appears to 
have no less admired the talents of Roscoe. One of hcf MS. 
poems, written about 177^ contains the following line^, irbich 



Memoir of William Roxcoe, Esq. 197 

at once prove the poetic powers of the author (destined after- 
wards to b«come the mother of an emineDt poet), and shew her 
discernment ip detecting, in the unknown attorney's clerk, the 
genn of future eminence : — 

. f But cease, n; Muse, unequal to tbe task. 
Forbear t^e effort I and to noblei; hands 
Resign the lyre ! Thee Eoscoel every Muse 
■ Uncalled attends, and unlnvolied inspires: 
In blooming shades and amarantbioe bofrers 
They weave fjie future garland for thy brow, 
'And wut to. crown thee with inunortal fioie ;— 
Thee Wisdom leads in alt her lovely walks, 
Thee Genius fires, and moral beauty charms ; 
Be it thy task to touch the feelinj; heart, 
Correct its passiuni, and ciait its aims j 
Teach pride to own, and owning to obey 
Ftur Virtue's dictates, and her aacred laws ; 
To brighter worlds shew thou tbe gioilous read. 
And be thy life as moral as thy song." 
Congeniality of disposition and genius drew close the bands 
of friendship between this lady and Mr Uoscoe ; and it is worthy 
of notice, that his first published production, the poem entitled 
Mount Pleasant, written at the age of nineteen, was originally 
inscribed to her, although, when printed, the address was 
omitted. 

This poem, which exhibits, with considerable power of versi- 
iicatioh, a warm poetical feeling of the beauties of nature, is 
still more remarkable for the indignant apostrophe to Britons 
oh the slave-trade ; an expression of generous sympathy with 
tbe suffering sons of Africa, which it required no inconsiderable 
' share of moral courage to promulgate at that period, and in the 
chief seat of the odious traffic. 

" shame to mankind I But shame to Britons m{)gt, -

Blast ev'ryjoy, and add to ev'ry ill; 
The trembling limbs with galling iron bind. 
Nor loose tbe heavier bondage of tbe mind." 
'I'hese lines are here chiefly quoted to shew how early Roscoe 
denounced the traffic in human flesh ; and that the love of li- 
berty which marked his whole life, was in him, not the crea-

While Roscoe was thus improving his litflrary taste in the 
moments snatched from the fatigues of his precession, he devo- 
ted no incondderable portion of bn attaitioD to the stud; and 
promotion of the fine arts in his native town. He was the chief 
instigator, and most active member, of a small society formed 
here in 1772, "Jbr the encouragement qf desigmnff, drawing, 
and painting;'" and he nsad before that associadon,' at one of 
its first meetings, an ode, addressed to the institution, which was 
afterwards published with the poem of Mount Pleasant, in 
1T77. 

Soon after th« termination of his articles of clerkship, Mr 
BoBcoe entered ittto partnership as an attorney with Mr Aspi- 
nall ; and in this professibn be continued, first with that gentle- 
man, and afterwards with Mr Joshua Lace, until tbe year 179& 
It is proper to remark, that Mr Roscoe, though eminent a* a 
practitioner, never relished his profession, and had always ex- 
pressed his determination to retire from practice as an oUomey, 
whenever the possesion of a moderate competence should liable 
him to devote his attention to Uterary pursuits. He continued, 
however, for several years to attend sedulously to his budnese ; 
but it was not until the year 1781 that the profiu of his exer- 
tions enabled him to many ; when be was united to Jane, the 
second daughter of Mr William GriHies, a respectable trades- 
man of Liverpool. 

This union was productive of the utmost domestic happiness 
to the subject of this memoir, and made him the happy father 
of seven sons and three daughtere ; all of whom, except a 9m 
and a daughter, survive him. 

For s^eral years after his marriage, at intervals of leisare^ 
he omtrived to increase those rich treasures of literary infonna^ 
tion, and to cultivate that taste for the fine arts^wttidi gave a 
peculiar charm to his conversation, and paved the way to Ihb fu- 
ture celebrity. 

In the year 1787, the agitation of the abolition of the dave- 
trade drew Mr Roscoe into the field of political controverv^ ; 
and he became the author of two anonymous pam[^letB on that

nif>nwe his Uste, with the. wisdom and art oi toemer ages. 

Id the year 1789, after much previous study of It^ian litera^ 
ture, he begsn to devote hiiaself to the ot^cct of his early atalu- 
tkm, the Life of Lorensm the Maga^cent. In the course of 
that year he wmmuiiioated his intention to his Tidued friend 
William Ctarln (wbo, oq account of his health, in the autumn 
of 17S9»' had 4xed bis residence at Viesole, near Florence), and 
ceqanted his asastanoe in collecting manuscript documents re- 
latingjto the subjeot. The fruits of the friendly exertions of 
that amiable nun are bast ^ven in Koscoe's own words. 

— '" An istitDBte friend, with whom I had been many yearR 
united in studies and affection, had paid a visit to Italy, and 
bad fixed bis winter residence at Flm^nce-. I well knew that I 
had^oaly to request lus assistance, in order to obtain whatever 
information he had an opportunity of pro^itiog, from the very 
i^t which Was to be the scens of my intended history. My 
inquiries «er« paiticularly directed to the Laurendan and BU 
canK Uikranea, which I was convinced would afford much ori. 
■ffiai and interesting information, k would be unjust m^ely 
to s^ that my friend aJKirded me the assistiince I required ; be 
mnt for beytmd even the h^>e8 I had fonned, — and his return 
to bis native country was, if passible, rendered still moce grate- 
fol to tae, by the materials which he had collected for my use *." 

Of these documents several are published entire in the a[>< 
pendix to Boscoe's wcM'k, effiedally the poems of Lormao; the 
existence of which had escaped the knowledge of the ;fonner 
biographers of die Prince^ Merchant. 

From, a very early period, Mr Roscoe had taken a deep in- 
terest in political matters. In the year 1788, he took an active 
part at the meeting which, in LiverpoiJ, as well as in other 
puts of England, . assembled to commemorate the centenary of 
the Revolution that expelled the family of Stuart from the 
throne of these kmgdoms ; and he composed an ode, which was 
rcdted on that occanoo, 

, I« the ftdlowtng year the French Bevoluti<Hi broke out; and, 

in oommon with many warm and generous spirits, he hailed iu 

fair and auspicious dawn with all the devotitm of a friend to the

These brilliant and exulting strams were poured forth in the 
year 1789, while " the Genius of French freedom," m the ner- 
vous language of Carrie, "'appeared on our southern horizon with 
the countenance of an angel," — and ere she had yet " assumed 
the features of a demon, and vanished ia a shower of blood.*" 

Mr Roscoe had, on several occasions, made himself cons^ncu- 
ous by his attachment to the cause of civH and religious liberty, 
in such a degree as to attract the notice of several eminent states- 
men, and particularly dt the late Marquis of Lansdowne, with 
whom he maintained a close correspondence until the death of ' 
that nobleman. Literature, and especially politics, were the 
subjects of their correspondence ; and the letters show how con- 
siderable were the parliamentary reforms advocated by the Whig 
statesmen of that period. 

The violence of the second French National Assembly, in the 
two succeeding years, alienated a great many of their admirers 
in this country ; but many good men still hoped that the fei-- 
ment would subside into rational liberty, and deprecated the 
evident hostility which our government begun in 1792 to exhi- 
bit. Among the latter was Mr Roscoe. On the appearance of* 
Mr Pitt's famous proclamation against sedition, the minds 6t 
men were much agitated, and greatiy divided. The friends of 
the minister in Liverpool convened a meeting to thank his Ma- 
jesty for the proclamation. Mr Roscoe, semndedby the late 
William Rathbone, succeeded in carrying a counter-address ;

'On theitHsakiug out of the war with France, Rosooe again ap- 
paaiB OS a political ^rriter. HeioTeigbed a^nst the unjust and 
impolitic interference of this goveinment with France ; and, in a 
pamphlet entitled " Thougltls on the late Failures," published 
in 179di he attributes the mercantile distress of that period to 
the ccmsequNices of our meddling pohcy, a sutgect which he re- 
sumed in 1796, in " Jn Expoivre of the FaUodesof Mr 
Burke't'^ ce)ebrated iuveciiTes against the French Revolution. 

We come now to the priocipal event in the liistory of our 
author, the publication of " the Life <:f^'LoretiZo de' Medtci," 
wjiich appeared in the winter of 1795, in two volumes quarto. 
The work was fainted by John M'Creery in Ijverpool, and is 
a fine e^ieamai of provincial typography, both for accuracy and 
elegance of executtOD. 

The sensation produced by this work was immense ; Uie first 
edition was rapidly exhausted, and a second was demanded by 
the public within a few months. Letters of the most gratifying 
kind were showea'ed on the author from high literary authorities 
in all quarters. Among others, the late Earl of Bristol, Bishop 
of Derry, then reddent at Rome, hailed with the highest en- 
comiums the appearance of an English work, which was the 
suEprise and envy of the Italians ^emselves ; and he imme. 
diately wrote to the publisher to know " what present of Italian 
books would be most acceptable to the accomplished author."' 
Ita success on the continent was no less gratifying. Besides a 
reprint pf the ori^nal, the work was speedily trandated into the 
Italian, French, and German languages ; ^d it procured for 
BoscQe the esteem and correspondence of some of the most emi- 
nent literaty men of Europe.

which has gone tbrtnigb bo many hiq^ editiona in Britain, which 
has been translated into the. most polished Umguee of the con^- 
nent, it is not my intention now to criticise. J flhaJl^witept my- 
self with remarking, that the author's intimate acqiciintwc« 
with the literature of Italy has excited the surpnEe even of 
ItalWs ; and I well recollect the incredulous stare with wbiob 
an Itahan nohleman, of great literary taste and lofoniutlipn, x^ 
ceived my assertion that Mr Roscoe. had never been out, of 
England. 

The success of the Life of Lorenzo spears to have cootirm- 
ed the author''B intention of relinquishing his practice as aa «u 
torney ; and, some time after that event, he entered his name 
as a member of Grey's Inn, with a view of bemg called to the 
bar. This determination, however, he alto reUn^uisbed, upon 
keeping a few terms. 

In the year 1797, while his name remained on,the books of 
Grey's Inn, he paid a visit of some length lo LondfHi. In con- 
sequence of his literary reputation, and his intimacy with Lord 
Lansdowne, he was introduced into.Oie first literary and various 
political drcles : in particular, he used to state, that be then had 
the pleasure of becoming personally acquainted with Mr. Fox 
and Mr, now Lord, Gr^y.; and he foriaed b^des many v^ued 
private frieridships, which were dissolyed on)y by death. An:v»3^ 
those who then more particularly gained his esteem he, often 
mentifHied Ur Moore, author of Zeluco, of the sprifed ". Fie*> 
of Manners in Italj/," and of a "Journal (^.a Residence m

To relieve his mind from the fatigue of more intense researoh^s^ 
he this year translated into Ej^lish vej-se liie Ba^a^ Tsniilki

able tact and spirit. His more arduous occupations were the

of Letters, with a view to the Life of Leo X. ; a subject which 
had been recommended to him by Horace Wnlpol^e (Lord Or- 
ford), and some other literary friends, after hig successful publi- 
cation of the Life of Lorenzo the Magnificent. 

In the year 1798, the want of a public reading-room on a 
better footing than Liverpool then could boast, caused the 
foundation of our Athenseum. The plan suggested by Di: 
Rutter was warinty supported by Mr Roscoe, Dr Currie, Mr 
George Case, and aome'other genllenien, who, exerting their iii- 
fiueoce among th«r friends, obtained so general a subscription 
in Liverpool, that the foundations of our magnificent Consulta- 
tion Library and News-Boom were speedily laid, and a consi- 
derable coUectifm of books soon formed. In this institution, as 
credltaMe to his naiive town, Mr Roscoe always took muc^ de- 
Kght: 

The numerous strangers who were now attracted to ~Li\^. 
pool, chiefly by the reputation of dur disUnguished feltow-dtizcn, 
caused such encroachments on bis time, notwithstanding his re- 
tiretnetit from buMbess, that be resolved to retreat into the couo- 
tiy; and with this view he purchased lialf of the estate of AI- 
l^rton fn^ the representatives of Mrs Hardman, and removed 
to that beautiftil spot in 1199. In a playful letter to Fuseli the 
pubter, Mr Roscoe mentions his retnoval, and his intention of 
not agiun embarking in any kind of business, but of dedicating 
biitaBelf wholly to agricultural and literiuy pursuits. His tastes 
were simple, his views moderate, and bis means fully compet«it 
to realize his jdans ; from whidi it is greatly to be lamented 
that any circumstances should ever have induced him to deviate. 
While employed as a professional man to arrange' the involved 
amoems of- the bank of Messrs J. & W. Clarke, he was thus 
brought into contact with Sir Benjamin Hammet, a London 
Banker, who held acceptances <^ the Liverpool Bank to an im- 
maiK amount (I am informed for L. 800,000). Hammet was 
so struck with Roscde's alnKty in ari^nging the afbirs of his 
irinidB, that he inshed him to become a partner in the concern. 
This be r^)eatedly refused ; but -Hammet threatening, in case of 
bisrefuafd to JMn the concern, to make it bankriipt, Roscoe, satis, 
fieti 'that the assets were, in ordinary times, more than sufl^ent 
to eov» the demands against the bank, finally consented, and

WfaUe thus employed, the hours tAuA he was now eaabled 
to devote to the history of Lea were abstraoted from the period 
usually dedicated to repose or Rcreation. Yet, mth' aU these 
demsnda oo .his sppticatJou, the interest he always fdt on grieat 
political questioos did not suffer him to viewin nlence the crisis 
di 180S ; but called fwth his pamphkt entitled " 0b9trvaiion» 
en the relative tituatkm of Great Britam and France f a tract 
in which be has recorded his detestation of war, and bis anxiety 
to see the two foremost na^ons of £uK>pe «igaged iti the leM 
guilty livalry tor pre-eminence in the arts of peace. 

In 180% the Botanic Giarden of Liverpool was estaMirfied, 
chiefly through the influence of Mr Boscoe, and, at its openmg, 
he delivered an address to the proprietors, which was pritited. 
In this establishment . he always took the interest of a parent 
in a &vouiite child. Under his auqiices, and d>e OHmnntnate 
skill of Mr J<^n Shepherd, the CuratOT of the garden, it speevb'' 
ly became conspicuous among boUnical establishments, arid it still 
ranks among the first in Europe. 

In 1805 he completed his history of " the h^e and Pmt^catt 
^Leo. XT' which appeared that year in four volumes 4to. 

This elaborate work had been the fruit of much researrlb, of 
intense previous stady, and ww always regarded by its snthor 
as superior to his Life of Lorenzo : yet it wasnot sD'^oamMy 
recaved by the British public ; a circumstance with some truth 
Bt£rU»ted to the violent attacks on it in several t£ our periodiod 
works. 

The boedHty of lome of the reviews was evidently p todwciefl 
by pt^tical ranoour toward Roscoe as an opponent of tbeioiilift-

from anger at the manner in which bebad-treMed dWcharaeter

On the ^peanmce of die British critidsms, Mr Bosem prB> 
pared a full aoawer to the objections of the reviewers, but this 
reply he never published; contenting himself with inserting a 
iKort abstract of it in the pre&ce to the second editim, which 
appeared in 1806, within a year from the publication of the 
first The chief objections, io addition to the criticisms alxm 
stated, were, that he was fond <tf paradoxical opinions,— -as in-

Borgia, — and in his doubdog wheth^ Pope Alexander VL was 
Itained with evo'y crime liud to bis charge by hia numenins

had made needless inaovaticms on our language. ' Theee charge^

majcffity. ■ ■ , - . i 

His parlmmentary career was of ^rt dnratkni but he bad 
the satiiAction, in that short period^ of dedmng his smtiiaMitt 
OR sevmd eubjectB in which he felt a deep intemt. He spoke 
and voted for Sir Samuel Romilly's bill ^r rendering real 
estates tubject to simple contract debts ; he had the happiness to 
lift his Toice m Farliwiieat for the abtJitimi of the ^ve-tnkde, 
and to Gee that great act of national justice triurapbiuitly eaN 
md; he had an opportunity of adVocstiog the clumst^ our 
Roataa Catholic brethren to an equality of pc4itJcal rights ; 
aad he delivered his sentiments with indignant eDet;gy on the 
dtsmissol of the Whig admkustnttion in 1807, on th^' axtemft 
to redeem the pledge givot by Pitt at the period of the Iridi 
Union; af^ge by themselves always considered as jnst and 
expedient. 

Mr Roscoe's chief parliamentary friends at that time, were, 
Mr Whitbread, ^r Samuel Rotnilly, and Mr William Smith ; 
but he never permanently attached himself to the ministry ; and 
waa l^ -tbetD regarded as a persmi who would rather act on his 
own views of what was r^ht, than enter into the traatniela of 
party. 

■ Oh the dissrihitlan of Parliament, he received another requi- 
sition tb'ofi^r hitnaelf for Liverpool, and was escorted into town 
by a very numerous and respectable cort^. His oppoooitt, 
however, had succeeded in pr^udicing many of the populace 
against him, espedAtly on the ground of his vote for the aboli- 
tion of the Slave-Trade — a traffic which they had been taught 
to consider as essential to the commercirf grestness of the pbrt ! 
and the rage of zealot^ was kindled against him for his speech 
on the'CathoNc Question. The consequence was, that, on'the

1809, he presented to the Linnean Society his valwdile paper 
" On a new arrangtment of the Scitamtnean order cf- piamts,"" 
which appeared in their Transactions, and established hit olaiin 
to the diaracter of an original thinker in this elegant depart- 
ment of natural history- His reputation, nill saore daan.tbe 
cltoms of private friendship, led Sir James Edward Smitih to 
institute the genus Sotcoea, which now contaiiu many speoWa of 
that beautiful order. 

A ^mihirity of polideal prinrifJes, and congraiabty <f taste 
for agricultural improvements, had for some time madeRoeeoe 
aequainted with Mr Coke of Norfolk. In 1814, be was in- 
tited to visit Holkhamy the splendid seat of that emimnl agri- 
culturist. There he found ample employmwt in the magni- 
ficent library, collected by the late Lord Leicesttf, nncle to 
the present possessor, a nobleman who, with vast wealth, fios- 
seseed a highly cultivated mind, end a passion for collecting 
books and manuscripts. It was well known that the collection 
was immensely rich in classical manuscripts and unpublished 
works on Italian history. Mr Roscoe readily undertook the 
examination of this superb oJlection, which .had afforded to 
Drakenborck the manuscript copies of lAvy employed in his 
valuable edition of the Roman Historian, and wtucb, among 
600 manuscript vtdumes of ecclesiastical anaals and Italian civU 
history, was discovered by Mr Hoscoe to contain one of the lost 
Volumes of Leonardo da Vind's Treatises on Mechanics, and 
the long d^tored and precious volume in which Baffaello, at 
the desire of the Pontiff, bad made pen drawing* of the re- 
mms of ancient Roman magnificence, illustrated by short de- 
scriptions in his own handwriting. Mr Roscoe undertook to 
make a cataloffug raiaonnie of the manuscripts of the colleaboa 
—a task which he some years afterwards, with the assistance c£ 
Mr Maddm, now one <^ the librarians of the British Museum, 
fully accomplished. This catalogue (of which a EJiort account 
was given to thu Society a few years ago) extmds to fbur or 
five iiaxk folio vcdumes, and . is enriched with engraved Jiic 
timiies and iUuminated ornaments. ' 

The manuscripts had been little attended to for many years. 
Most of them were in the original coarse paper covers, and

siHne were injured by damp and time. The whole were lome 
time afterwards amugned to Mr Roscoe's care, who put them into 
the hands of our eminent binder the late Mr Jdin Jones, who, 
by great industry and skil], succeeded in restoring cnimpkd vel- 
lum to its ori^at smoothness, in pasting torn leaves witbwon- 
derful neatness, nnd wbo bound the wh(Je cdlection in a du- 
rable and degant manna. An andent and admir^le Hebvew' 
manuscript of the Pentateuch *, written in a beautiful hand, on 
deer-skins, ftHiniDg a roll thirty-eight feet in loigth, was mount- 
ed, by the same ingniious an\st, on rollers ornamented with di- 
ver bells, under the direction of a learned Rabin, who believed 
the manuscript to be an eastern transcript of great antiquity. 

Toward the close of 1815, by one of our too frequent oocn- 
nmxiid convulnons, and by the extent of their acciHnmodations 
to persons engaged in bustness, the a^rs of the bank in which 
Mr Hoacoe was a partner became involved, and the bouse found 
it necessary to suspend payments. Vae four years Mr Roacoe 
devoted hims^ to the arrangement of their affairs ; entertaining 
throughout the most sanguine hopes of being able finally to 
dtscbarge all their engagements, as the joint property of the 
partneni was valued, at the time of the suspension of payments, 
at Gonuderably more than the amount of their debts. The de- 
preciatHH], however, of that property, combined with other cii- 
cumstances over which Mr Roscoe had no control, prevented 
the accomplishment of his most earnest wishes, and in 1890 be 
became a bankrupt. Previous to this (in the year 1816), his 
noble library, his fine collection of prints and drawings, and bis 
curious collection of poolings, were dispersed, and the proeeeds 
of the sale were applied to the payment of the debts of the 
house. It will convey some idea of the collection to state, that 
the books, consisting of about SOOO works, s(dd for no less a 
sum than Ij. 5150; the prints for L. 1886; the drawings for 
L.750; and the pictures for L. 3999; making a total of 
L. 11,025. 

The beautiful sonnet written by Mr Roscoe (Hi parting with 
bis library, was given to a friend, and handed about in manu- 
script ; but the Reverend William Heloe has since inserted it,

presented tfasni to Mr Boscoe. The ^ft, however, was firinly 
but gratefully declined ; and the subscribers resolved to present 
the collection to the A^enseuni Library, to be kept together aa' ' 
a testimony of their esteem for theii respected friend ; and of that 
lUjrary the collecrion now forms a distinct part. 

A selection from his pictures, comprizing spedntens of art 
highly illustrative of the pr^ress of painting, was purchaaed by 
several of the same geoUemen, at a liberal price fixed by Mr 
Winstanley and myself, and presmted to Hike Royal Institution 
by those admirers of Roscoe. This collecta>n cost L. SO, and 
forms an interesting part of the objects which attract strangers'

Soyal Institution originated, and' was drawn up bymeinl^lS;< 
aUbough it was carried into efiect^uring my absence on tbe Ccm--

HiBhiimanity and amiabie mind revolted from the ^-equency of 
executions; and he ei^erljr desired to see those statutes wliich 
awarded death for trifling (fences, and ore too bsrbaroui to be 
aifinved in die present day, expunged from the code of BritiA 
jurisprudeDce. -Shortly before the period of tue mUfortunes^ 
llis-attantion had been turned to the subject of penal law and 
]»ison discipline. In 1819 he published Ms traat, entitled ** Ob- 
aervations on Penal Jnriapritdencet and the JtefiirmatioR of 
Criminali ;" which was fcdiowed, between that peiiod and 1 83S^ 
' by two other dbserlations on the same subject 

The principle of the system which be advocates is, that the 
only legitimate ol^ect of punishment is the prevention of a 
repetition of the crime, by a reformatiwi of Uie ofTeoders ; which 
ettict be proposed to accomplish by hard labour in penitentianes, 
and by moral iustructiwL He d«iies that wehaveany right to 
punish fair the mere benefit to sodety of the example. He in- 
veighs «gaimt the barbarous maxim that revenge or expiatioit 
for the injury committed ought ever to be the principle of pen^ 
Je^alatJon; and cannot admit that retributitm to the injured 
party can be the [»:<^)oged end of puoisbment. In the thini 
part of his essay, he seems to doubt the propriety of the puo- 
ishment of death in any case,— Part iii. p- 106 ; but, al all 
events, he considers that it should be reserved for four or five 
crimes of the blackest dye. These essays contain the out- 
line of some principles which are now generally acknowledged ; 
U)d -if the humanity and generous spirit of the author have led 
him to form a too favourable estioiate of human nature, and to 
overlook some difficulties in the practical application of his prin- 
ciples of legislation, we cannot but admire tbe benevolent enthu- 
uasm and earnest appeal to the best fedinga of our nature whidi 
are stampt on every page of his treatise. 

In his second tract he had pointed out the evil consequences 
bkely to result from too great severity in prison dtscipline,.and had 
entered a warm protest against the horrid punishment of long-con- 
tinned solitwy confinement, as a general measure for effecting this 
reformation of offenders. He severely commented in the third 
part on tbe atrocities which appeared to have been perpetrated in 
the Auburn Peoiteatiaiy in the State <^ New York. This drew 
him into a long controversy with several American writers in the 



214 Memoir of WiUiam Soscoe, Esq. 

latter years of his Kfe ; dnd to the zeal with which he devoted hitn- 
aelf to plead the cause of the outcasts of society, we have to ascribe 
die first serious shock to his general health, as I shall by and 
by have occasion to notice ; but he had the bapf^ness to find, 
after much angry discussion in the newspapers of the westnti 
world, that his argumentB against solitary confinement, whidi he 
stigmatized as the utmost refinement of cruelty, and utt^ly in- 
^ectual as a punishment, w^e not lost on the Americans. The 
infirm staleof Mr Roscoe's health at that time brought me much 
into contact with my venerable friend ; and when he leomt Jrom 
various quitters that the change which was taking jdace in the 
prison discipline of America was in no small degree attributed to 
his expostulations, I heard him repeatedly declare, " that no 
lit^vry distinction had ever afforded him half the gratification 
he received from the reflection on the part he had taken on this 
great question ; and he expressed his satisfaction that he now 
mi^t be permitted to think that he had not lived altogether in 
van." 

I have, in notidng the conclusion of this controversy, onti- 
dpaled some events of his life to which we must now return. 

When released from the harassing cares of business, the 
mind of Mr Roscoe, with the elasticity and application of youth, 
diligently entered on various literary prefects. Since the first 
appearance of the Life of Lorenzo, he had obtained from Italy, 
and elsewhere, various documents illustrative of that work. 
These he prepared for pubhcation, together with some strictures 
on the manuOT in whitih the character and biography of Jm- 
reozo had been treated by Sismondi and some other writers: 
This work appeared in an 8vo. volume in 18S2, under the title 
of " IlkistnUioni of the Life o/* Lorenzo de' Medid^ The 
strong terms in which Sismondi accused Mr Roscoe of par^ 
tiality to ihe Medici Family, and of palliating th«r crimes, drew 
forth an able and indignant answer ; yet, it is {^easing toreflect^ 
that when Sismondi, a few years afterwards, visited Et^jlaiid, 
Mr Roscoe formed with him a personal acquaintance in no way 
affected by their literary controversy. 

About the same period, Mr Roscoe publt^ed an ambling 
" Memoir of Richard ' Roberts,"" a self-taught linguist, wdl 

Cxwlc

known in Liverpool by tfae extisordinBT)' number of languages 
whidi he esa road, no leas tiuat hy the filth of his person. The 
profits of this publication Mr Boscoe humanely dedicated to the 
use of this singular person ; whose intellect, defective in every 
thing but language, renders him as helpless as a child ; and Ro- 
berts may now be seen in whole clothes, with his p(n'table U- 
Imiry stuffed, as in former times, between bis shirt and his skin ; 
for be disdains a Hzed abode. 

An {^f^ication having been made to Mr Roscoe to become the 
editor of a new edition of Pope's works, and to furnish a fresh 
life of the author, Mr Roscoe engaged in it with all die ardour of 
a poet, having ever been a warm admirer of Pope's genius. 
This, was no triflii^ task — for he added notes on the poems with 
much care ; and is the life, wbicb forms the first volume of that 
edition, defended the talents and character of Pope from 
sundry imputations cast on him by Mr Bowles and others. 
The date of publication was 1824. 

About the same time, he superintended a new edition of the 
Ltaes qf Lorenzo and Leo, to the latter of which he added 
many new notes. 

. In 1824i, Mr Roscoe was elected a " Royal Associate" of 
the Royal Sodety of Literature, founded by his late Majesty 
George IV. A pension of L.lOO a-year was awarded to each 
of ten associates, which Mr Roscoe enjoyed for three or four 
years ; but which, from the neglect of providing a permanent 
fimd for the purpose, would have ceased about the time of his 
decease. The great gold medal of the Society, value 50 guinea^ 
was also awarded to him as an historian, two years before he 
died ; and it remuns with bis family. 

It would be unjust to omit, that the misfortunes of our dis- 
tinguished fellpw-eitizeo, called forth the warm sympathy of 
bis munerous friends, and prompted them to take steps for secu- 
ring him ag^st their immediate consequences. It is more neces- 
sary to state this, because many unjust imputations have been 
Tented against the inhabitants of Liverpool, on account of th^ 
supposed neglect of Mr Roscoe in his adversity. There was consi- 
derable delicacy necessary in the steps which were taken to testify 
their esteem and attachment. Mr Roscoe had. a noble and jnde- 



216 Memoir of IViUiam Roscoe, Eaq. 

pendent mind. He bad steadily! ixfiised the proffered g^ft/'of a 
valuable selection fronr his Ubrary, eyep .after it had l>eeii for 
that purpose bought by his friends at the ealci and those who 
had the pleasure of being intimate with hiai, we)! knew bon" 
necessary it would be to keep him in ignorance oF what was in- 
tended, until it was accomplished. During a second visit wbteh 
he made to Holkham, a private fund was quickly subscribed 
among his friends, for the purchase of an annuity on the. lives of 
Mr and Mrs Roscoe. The delicate task of cotanumicating what 
was done devolved on me; and in the corresptH^kmce which 'en- 
sued between us, though his piide of independence' was at first 
alarmed, the example of his friend Charles James Fox, iiader 
similar circumstances, was successfully urged, to leconcile bis 
mind to receive this spontaneous homage to his tal^its and his 
wOTth, from ^ncerely attached friends. 



We have already noticed Mr Roscoe*s eariy t 
botany, and his critical l^xiurs on the wder ScUamine^e, to 
which he had long paid much attentitn, sdmulated by the.con- 
tinual additions thb order was receiving from the East and 
West Indies. The number of new species wludi the judidous 
. care of Mr Shepherd, the skiU'ul curator of our Botanic Gat- 
■den, had successfully cultivated, together with tiie dried speci- 
mens which Mr Boscoe rec^ved from various quarters, deteiv 
mined him to publish a work containing coloured figures of 
new or interesting species, with botanical dcscripbona. Tlus 
^ve rise to the moat splendid botanical work that ever issued 
from the provincial press of any country ; which occupied much 
of his time during the latter years of his life, and was only com- 
pleted shortly before his death. Of thb superb work, he [urint- 
«d too few copies ; and before the second number came out, 
there was a necessity of reprinting addititMial copies of the first. 
The work is highly prized by botanists ; and is porticul^lj 
valued on the Continent, where, fnnn Uie small number of im> 
pressioBs which Mr Boscoe could be induced to throw off, it is 
extremely scarce. Many of the beautiEul figures m his work 
-are from bis own spirited sketches ; but the minority of tben 
are the productions of the pencil of hb dat^htcF-in-law Mrs 
- Edward Roscoe, or of Miss R. Miller of this place.

My acquidDtance whir Mr Roscbe commeDced in 1806, and 
I soaa h»A the fdici^ of bfttog received as an iDtimate friend. 
Prom 1810 I was further honoured by b^ag consulted as his 
'physician, in which capacity I watched with much anxiety over 
his declining health. From the dine of the first derangement 
of the affmrs of the bank, the immense mental and bodily exer- 
tions which he made produced great inroads on a constituUoa 
naturally good. He then began, on much application to any 
fiUbJKt; to be am^ with octiasional faintness ; and once, in 
1816, he was attacked at the bank with a slight loss of memory, 
which speedily vote off. His habits of intense study, after 
this period, produced similar efiects ; and while engaged in the 
controversy on prison disdpline, after writing for the great- 
est part of a nl^t, to overtake a ship about to sail for America, 
he was affected in the winter of 1827 wiih partial paralj»s of 
the muscles of the mouth and tongue. I was immediately called ; 
the patient was freely bled-^^n which he recovered his speech : 
and the introduction of a seton in his neck removed the panu 
lytic affection of the mouth. Intense study was forbidden : 
and after a period of perfect relaxation from bix literary occu- 
pations, he recovered sufficiently to be able to complete his 
botanical work, the catalogue of Mr Coke's Hbrary, and to cor-' 
rect for the press his latest tracts on prison discipline. It was a 
great satisfaction to find his intellect quite entire, and it remained 
so until within an hour or two of his death. His bodily feeble- 
ness, however, gradually increased; yet, by the affectionate 
care of his family, his infirmities were little felt. His amuse- 
ments were vaiious reading, the illustration of his son's transla- 
tion of Lanzi's History of Italian Fainting, by a small collection 
of engravings, together wit^ putting the last hand to his botani- 
cal work. He was unable for the fatigue of receiving much 
company, or of seeing strangers, for some time before his death : 
yet he loved to converse, with a few friends, and took a lively 
into^st in the pcJitical events with which the last year (1830) was 
pregllant. On the French revolution of July, he wrote a long 
and earnest letter to M. La Fayette (with whom he had before 
oceasicnally ocHTespcHided), urging him to use the influence of 
his name and pt^Urity, to induce the French nation to spare 
■the lives of the ministers then under arrest; pointing out how a

Betides his published works, Mr Roicoe has left behind him a 
large mass of papeis, and an extensive and valuable «orFeq)oiid- 
ence. 

AmcHig the former are various dissertations on the &ie arts, 
some of which appear in a finished state. In the year 1814, 
Mr {Roscoe had proposed to the writer <^ this memoir to under- 
t^e the translation of Lanasi's Sioria PUtorica deUa SaRa, and 
he eng^ed to furnish notes, and a preliminary dissertation. I 
had made considerable progress in the translation, when Mr 
iRoscoe's misfortunes, and my own professional avocations, in- 
terrupted the work ; which has since been well executed by his 
son, Mr Thomas Roscoe. Among the papers of my venerable 
friend, I find a very interesting introductory dissertation, in-

In person, Mr Roscoe was talt, aad rather slender. - In early 
life he posGessed much bodily activity : his hair was light au- 
buru, almost iDcltning to red ; his full grey eye was ciew omI 
mild ; his face espressive and cheerful. Ab he odvancedia laici 
the benevoleut expressiou of his coimtenance remained, but the 
vivacity of the features was tempered iate a. noUe digaity, 
which it was impossible to see without respect and admicatioD ; 
while the mouth bespoke taste and feeling, and the clustering 
hoary hair round his temples gave. a veoeraUe mr to his manly 
features. 

There are several representations of him; but none et them 
appear to me so finely to express the characteristic touts of his 
head as John Gibson^s medallion. The portrait in the Insthu- 
tion, and Spence's busts, give us Mr Roscoe in bis dedine with 
great fidelity. Gibson^s marble bust is said to recall bis youth- 
ful appearance ; but the Terra Cotta medallion is Mr Rosooe, 
as I should wish to jemember him. I may add, that it has been 
exceedingly well copied in the fine medal, published by Mr Cle- 
ments of this town, from a die by Clint. 

Of Mr Roscoe's genius and acquirements, his puUisbed works 
present a better memorial than any panegyric can confer; but I 
may be permitted to state my conviction, after having examined 
a great mass of his unfinished manuscript dissertations, that, had 
he been'left to pursue his ori^al plan of literary retiremettl, 
instead of again plunging into the cares and anxieties. of busi- 
ness, he would have left behind a work on the History of the Fine 
Arts, far superior to any thing on that subject which British 
literature pwsesses. 

In public life, Mr Boscoe was a conasttot sad feMtless Aash-

He had deep and solemn feeliogs of devotioD, which it was 
nvt his practice to (^rude on his acquaintances ; but which he 
oocauonally expressed to his intimate friends in the language of 
heotfelt {nety. The beautiful invocation to the Deity, which 
he sulMtituted for the intended dedication of hb great botanicai 
worli, breathes the deep fervour of his adoration of the Supreme 
Creator; and is also r»narkable as the actual suggestion of a

a liberal and judicious pstnHiage of modest talent, struggUngto

On the Mode of delerminit^ Fossil Plants. By Professor 

LiNDLET. 

W HEN a botanist proceeds to the examination of a recent speci- 
meD of on unknown plant, he directs his views to certain pecu- 
liiuitieG in the oi^ans, both of fructification and vegetation, ta- 
fcoi together ; and from what he finds to foe their structute,' he 
judges oi the class, order, or genus to which it belongs. But 
as jn fossil plaits neither cdyx, corolla, stamens, nor pistilluni 
are to be recognised, ui <^nton has to be fbmed, not from the 



ass Professor Lindley on the Mode of 

consideration of a complex combination of characters, in which 
the loss of (me organ is compensated for by the peculiarities of 
those which r«nain ; but &om a few isolated tatA rery iai'perttct 
data, exclusivelj aflbrded by the remuns of the organs of vege- 
tation. Id the latter, unfortunatdy, thie modes of organization 
are not sufficiently varied to enaUe us to draw any precise cod- 
cluuons from their examinMion ; but, on the contrary, we are 
often obliged to Ite satisBed with a general idea only of the na- 
■ tare of the object of our inquiry. This is, perhaps^ not attend- 
ed with BO muc^ practical inconvenience as might be espeeted, 
in a getdf^ical point of view, because the end of soence will be 
sufficiently answered, if we can, in the first place, determine the 
goieral t^aracters and affinities of the plants of the former eras ; 
and, in the second, so exactly classify their fosal remwna, as to 
be aUe to rect^iae them, with such precision, as to render them 
available for the ideotificatirai of strata. 

It usually happens that die only parts wfaic^ are capable of 
bfflng ^amined in a fbsal state, are the intenial structure of the 
Stan, and its external siu-tace ; ti^ther with the position, divi- 
^on, outline, and veining of the leaves. Of these it has never 
yet happened that any one specimen has afforded the whole ; 
more frequently it is only two or three of those characters that 
the botanist can em|doy. 

Suppose that he has a fragoaent of the fossil trunk of some 
unknown tree ; if no trace can be discovered of its exact anato- 
mical structure, it may be pos^hle, at least, to ascertain whether 
its wood was deported in concentric zones, or in a confused man- 
ner; in the former case, it would have been Dicotyledonous, or 
Exogenmis, in the latter Munocotyledonous, or Endogenous ; 
if a transverse section should shew the remains of siououa un- 
cotmected layers, resembling arcs with their ends directed out- 
wards, of a solid bomt^neous chmncter, and embedded among 
some softersubstances, then it may be considered certain that such 
a stcan belMiged to some arborescent Fern. Bnt if the state of 
a fossil stem will admit of an anatomical examinaticm, it is ^ways 
dedraUe that it should be instituted with the assistance of the 
miooBCope. Naturalists have shewn the possibility of this be- 
ing d<Hie ; and if it should prove that the condition of fbssil re- 
mains it io general favourable to this kind of examination, more

t^^tu likely to be thzovn u{»d tbe «Umct Fkni than oould 
be otberwise ootieipated. If tbe tissue of s sma dioald be 
fnind eatirely cellular^ and it couU be sBtkCKtoriy nade out 
dutt no vasGular tissue whatever was oombined with it, the sped- 
men would, in all probalulity, have belonged to that diviaon of 
tbe T«^etable Idngdom, which, bebg propagated without the 
agency ofeexes, is by botanists called Cr3rptoganiia. A spedaieit 
(^ this kind should, howerer, be examioed wilh the most rigorous 
aocorat^ ; because it might hare beeu a sucouleot portioo of 
aame Dicotyledoiiaus tree, ia which tbe vascular systen was so 
stattered among crilular substances as to be scarcely disccniible. 
If the tissue should have coBUSted of tubes placed parallel with 
each fitber, without any trace al rays passing from the centre to 
tbe wcmnference, it would hare been Monocotyledonous or En- 
d^enous, even if there should be an appearanoeof ooncentric cir- 
cles in the wood; but if any trace whatever can be discovered of 
tissue cnMBing the loi^tu^iial tubes at rigbt«ng)es, from the 
centre to the circundmnce, then such a specimen would have 
been IMcotyledcmous or Exogenous, whether concentric circles can 
be made out or not ; for such an arrangement of tissue would in- 
dicate the presence of medullary rays, which are the most certun 
ngn c£ a Dicotyledonous plant. If, in a specimen having these 
rays, the longitudinal tubes are all of the same size, a drcum- 
stanee obvious upon the inspection of a transverse secticm, the 
^ant will have been either Coniferous or Cycadeous ; but if, 
aioraig the smaller tubes, which in fact are woody fibres, some 
larger ones are intenpersed »( a definite manner \ it would, in 
that case, have bekmged to some other tribe of Dicotyledons. 
It is indspensahle that the arrangementofttie'largertubea should 
have been definite, for appearances of the same kind exist in 
mudi Coniferous wood ; but, in the latter, they are scattered in 
am indcAnito manner among the smaller tubes, and are not ves- 
aels but t^rfindrical oavities, for the collecdon of tbe rennous ae- 
owion peculiar to the Fir tribe. Again, if tbe walls of tbe lon< 
gitudaial tubes of any foeul specimen are found to exhibit ap- 
pearanora oS little warts, growing from thar sides, such a speci- 
toesy had ocrtaiiily belonged to smne Coniferous or Cycadeous 
plast, no other tribes whatever possessing sudi a structure at 
tbe preseatdi^. Finally, if a trace of ■pith can be diacovered.

In Na 25 of your valuaMe Journal, pa^ SO, you have insert; 
ed an interesting paper on the vitality of toads by Professo*' 
Bocktand. If other experiments, partly siirlilar, btlended with 
fflimlaT results, are worthy of recording, you tflay Insert the fol- 
knviog-. 

On the aad June 1830, I placed threetoads No. 1, weighing 
6 draehms ; No. 3, weighing 17^ drachms ; No. 3, wdghing St^' 
drachnra, in separate flower-pots, covering the surface with a 
ble, as well as the b<de at the bottom. They were then burie<3 
about four feet deep in garden soil, and dug up on the 21st 
March 16S1, all desd. It appeared, ttowever, from the state 
of their mnalns, that they had died at diflb-eut times, the body 
of one being in nearly a perfect state, whereas of another noi 
tiling rennioed bnt the bones. Conceiving that the damp stat4 
f£ the soil might -have aJfected them, I placed a 4th in a vride 
mouthed bottle, cofk^ down, in a dry place, inserted a qulfl 
through the cork for the admission of air, and a 5th in a simi- 
iarbottle, well' corked, eotirdy exdudiftg air, whith died before 
I'was aware of it, in 48 hours*; proving very decidedly that 
air is ae eseenliat to tfcdr existeWce as to any other class of living 
enisiBls. No, 4, continued in apparency good health for about 
a fottoigbt : k tlien, how^vei', began to ^ew dgns of weakness^ 
" It is Bcarcely necessary to add, that the air In the bottle was totsllj uafiU 
ted ftr rapicatiini or combustion ; a lighted Upei plunged into It was immc

^^Is I had enclosed in the bottles, omUiiniog - the weights , of 
the toads and da^s of their confinement. It it dear, from 
these several experiments, that the commonly received b^ief 
fbat these reptiles qtn,exist in blocka of sUuie and steqia,<tf. adQ^ 
Toud, is perfectly lalse ; notwithstanding the almost numberleta 
instances on record, apparently ,well attefited, c^ thek vitaJity 
under the joint additional nngularity of exclusion of, wr and 
privatipn of food. My ^xjierim^ts. are, indeed, more to tha 
point of their inability to esist for any length of time unless 
amply supplied with air and food cf th^ own sel«clim), Xban 
Dr Buckland's ; for I should observe, that althou^ in the in- 
stance oiFNo, 5, absolute exclMsion of ^r, exclunoo of ibod it 
also implied, in the cases No. 1, ^ 3, both food and wr were 
both more or less amply supplied, for, in the flower'-pou I not 
only fpund several small scolopendra, but quantities of more 
minute inserts, cansistiqg chieSy of the Podura^fimetarta^ .Now* 
it is evident, that to that4eplh, air .must have penetrated,. or 
the insects themselves could not have existed ; and that it must 
have been to a degree quite sufficient for animal life, is equally- 
certain from these insects having descended so far from chtuce. 
There is still, however, considerable mystery in the history of 



jeSO Rev. Btiward Stanley on the VUatiliif ff Toads,

enough to meet with one of the many instances of toade sdid to

Qfi a Production of Najththaline tn on Oii-Ga» AppUfatu*-' 
By A,. ComiELL, Esq. F- It. S. E. ' Communicated t^ the 
Author. 

Poui^ white crystalliDe matter, said to have been d^xwtad hyi 
(ulygas, waa lately given me by Professor Jameson for Ghenucal 
exaojination. This matter ^as crystallized in thin taMes ad>.. 
tenDg^tosether id fi;roups, and possesiJiig a fine pe«ly huir», 
A partial dtscolorafioti was otcaMdned by the klteltnixti^ c^ k 
littfe impurity, confflsliiig of dxide of iron, mth some a^faeriug 
carbon^eous matter, which gare an empyreomatib mell wheo 
heated. The white crystals were fiMiod-to posseM thewiiU 
known chemical properties of naphthaline; and I tfaouJd'Kat 
have" thought it necessary to takesny ferther Kottce ef ihem, 
ba4 it not been that the source from which they pPbdeeded, and 
the drcuOistances under which tfiey were' forawdy were some* 
\)rliat peculiar, and may afford some ilhtstratioti of the ooDdidma 
necessary to the produenon of this body. ' 
. T)pon making inquiry at the place where Hw orjn^s wore 
produced, I was informed that they were &«t ' observed ia «r 
old iron pipe several feet in length], and a few inches iaintsmal 
diameter, winch had iive years ' before formed part of a ptivatb 
oil-gas apparatus. This pipe had been situated between the n- 
tort on the one hand, and the condenser and gasometer on> the 
other ; and when the apparatus was in operation, an taipyieM- 
matic oil used to be deposited in it, but no formation sf the 
white crystals had ever Ijeen observed during that peiSod. ' Tbe 
biaterial which had been employed for the production of thegas 
was at first whale-oil ; then palm-oil had been used ; aud^atter^ 
ly wjiale-oil had been ag^' employed. Some of the crystals 
which 1 saw tak«i out of the pipe ff«« nixed with a black soft 
pkdiy^Wkiag niM^^, which seemed t^ line its inside. 

When this dark, matter was heiated on platinum foil over the 

spirit-tamp, it fused at a moderate heat, and gave off dcnae 

white vapoursi When the flame of the lamp was brought in 

.Ktxnlact with it, it took fire and burned away, leaving a consinfe- 

•:ndd« icndue, wbicb was.atfACted by the magnet, and was it^n 

' more of' less oxUized. When some of the dark matte; wpn 



832 Mr Connell on a ProduB^on t^ NapkihaHtu. 
heated in a tube, it gave off at a moderate temperature a little 
napbtbalme, which condensed iu Uie upper partof thetitfbe,-««di^> 
as the heat was increased, a yellow fluid cfHiddnted «n the:^idea 
of the tube, which was to a great extent soluble in nloohd. > 

Several views maj be taken of the mode of productioo «£ the 
naphthaline in the gas apparatus. We mig^t suppose that" it 
bad been formed during the destnictiie distillation of 'one Sar 
both of the oils emjdoyed and depouted in crystals at the time 
of its formation ; but this view is opposed by the circumstance, 
that no naphthaline was observed whilst the gas apparatus was 
in operation ; and it is also improbable, that crystals of the nze 
obtained and so weO defined, should have remained during so 
long a period in a situation to which there was access of air, 
when the great volatility of naphthaline is considered. We may 
conceive, in the next place, that the naphthaline, after it had 
been formed by a new arrangement of elements during the des- 
tnic^ve distiilatioQ of the oil, was condensed along with some of 
the other products and held dissolved by them, until the solvent 
was decomposed or dissipated by the slow operation of time and 
the external air. Or, lastly, we may suppose that it was not 
formed during the distillation, but first existed only through the 
slow and spontaneous decomposition of some of those products, 
with access of air, after the apparatus had been laid aside. The 
last view is perhaps on the whole the most probable. 

The influence of external air in the |Huducti<Ht, or at least 
development, of naphthaline, baa been lately observed by M. 
Laurent, who found that naphthaline was not obtained in aU 
cases by the distillation of coal tar, and that its produt^ion was 
most certain when the coal tar had been long exposed to the 
air *. M. Reichenbach did not succeed at all in getting t\a^~ 
tholine by the distillation of coal tar, but the tar employed by 
him had been apparently recendy prepared +. M. Laurent al- 
so found that the action of atmospheric air was superseded by 
that of chlorine.

This interesting genus accords entirely in habit and in the atrao. 
ture of its perianthium wlih Cumtmngia, from which it ii, bow- 
ever, essentially distinguished by the circumstance of two. of the 
Btamens being sterile, and the absence of the membranous ptxots 
from the antliers, one of the cells of which is developed at. the 
base into a short spur-like process. The specimens whence th^ 
above description w&sderiv^, formed partof a small but valuable 
collection of plants made by Mr Bollaert, formerly ch^cal «h 
tastant at the Royal InsUtution, in the course of his travels in 
the interior of Peru. The Bingular circumstance of two of the 
Btamens \mag sterile, leaving four fertile, is worthy of particii-: 
lar notice, as fonning a remarkable exception to the law of de- 
velopment <^ organs among Uie Mottocotj/kdanex.

Besides the present, several other plants have been referred 
to Anthericti/m by the authors of the Flora Peruviana, which 
dearly do not belong to that genus; and among Aem thMr 
Anthericum phimosum and coarctatum are deserving of pardcu- 
lar notice, ae constituUng the rudiments of two new genera ap< 
pareDtly belonging to the normal group of Asphodelea. The, 
inferior or half-inferior ovarium, and the simple, inarticulate 
pedicels, have induced me to r^ard the Conunthereie as forming 
ft separate section of the order. The incumbent anthers and the 
^fid stigma essentially distinguish Pasithea, both from Conan- 
thera and 'Cumvdngia. 

It canndt ftil to be remarked, that the triple stigma and the 
completely inferior ovarium bring this genus very near to the 
Hi/poandea, affording one among many other proofs that might 
be adduced of the extreme difRculty, or rather utter imposubi- 
hty, of establishing absolute characters in Natural History.

A careful examination of the various species of Nierembergia 
and Petunia, which have fallen under my notice, has led ine to 

' the conclusion that they constitute but one genus, which is 
' scarcely of itself to be dtstingiiished from Nicotiana, except by 

' the foliaceons st^ments of its calyx. The tube of the corolla is 
found to be more or less dilated in different species, but thb 

. character cannot be regarded as of more than specific import- 
ance. The Nicotiana minima of Molina ft identical with Nie- 
rembergia repens. SatptgloisM agrees with Nicotiana in the 

' 8tnictui«'oP its calyx, and is only distinguished from' it ami 
Nieremiergia hy its sbme*hat irregular coroHa.

M. de JuBsieu has referred this genus to the Meliaceee, and ' 
in this opinion he has been followed by most subsequent wri- 
ters.: it appears to rae, however, to approach much nearar 
to the Eulacete than to any other family ; and I am led to be- 
lieve, after a careful comparison of their several characters, that 
few will question the propriety of ihe-place that is here asc%ned 
to it The genus has been omitted by M. De Candolle, in the 
published volumes of his invaluable Prodromus; so it is pro- 
bable that distinguished botanist had not made up his mind 
with respect to its affinities. Notwithstanding the ditference in 
habit and the structure of their leaves, I am inclined to think 
that Aitonia and Melianthus may he included in the same na-

Observatums upon iHe Structure and Development of the h^u- 
soria. 'By Dr Rudolph Wagner of Erlangen. 

Xhb fblloviiig obecTTBlioDs were made in the Hiiuner oC 16ftl» 
and I have to regret that the MUcnMcope vbich wu aafiffytd 
<iuiiK)t be compared nith that by means of which FroCasaor 
Bhrenbesg of Berlin was enabled to nuke his masterly resewrobaH 
into this department of nature. The iastrument employed w$f 
good, but of the old construction. The object-lenses were ma- 
nufactured by Utzschrmdtf and Frauenhofer ; and, although 
their defining power was excellent, they did not magnify more 
than from forty-eight to aisty diameters. 

I, Development of the Ht/dalina Senta '. 
: The ffytiatitia Smta is not uofrequently found in the neigh- 
bourhood, of Erlangen, in pools and morsheg, the surface qf 
which is covered with duck- weed, but it is not common in these 
situations, being more frequently obtained by keeping water 
«acloiad in eovei^ glwsee in the bouse for some days after the 
successive production and disappearance of other infusorial 
forms. This was the case with a natural infusion in which I de- 
tected, on the 3d November, a tolerable number of. the Hydatina. 
.These were of all sizes ; some were viable to the naked eye, 
but Btil> more distinctly with a common pocket lens. Some of 
tbe animals swun about in the water, but the greater number 
attached themselves by their posterior extremity to the walls of 
the vessel and vibrated freely the anterior part of their bodies, 
in all directions, in the fluid. On the sides of the ghiss, and 
still mare abundantly towards the surface of the water, was a 
brownish pulverulent mass, interspersed with small globular 
greenish grain^ — the dead bodies of the EugUna viridis, Ehren- 
berg. When a portion of this mass was placed under the field 
of the microscope, I observed a number of darker coloured and 
more distinctly defined oval or rounded bodies, which I imme- 
diately recognised to be ova, and there was visible besides a 
number of empty sacks, split up the middle, which had evi- 
dently been the envelopes of former ova. On the following 
• Figures illuHntiTe of the external fonn and intemal gtruclure of the

246 l>r Wagner on the Structure and 

day, the 4th November, the number of tbe animalcules had in. 
creased, as well as that of the empty sacks adhering to the sides 
of the glass. A number of new eggs had also been laid, which 
were chiefly collected towards the surface of the water. A glass 
wiU) a magnifying power of three, distinctly shewed, in tbe 
grown animals, a neariy ripe ovum ; <^ers were destitute of tbe 
round dark point bende the intestinal canal ; these had probably 
a short time befiwe evacuated their ova. Besides ijas Jtydatma, 
there were many still smaller infusoria, which swam about n^ 
much vigour, and appeared, under the microscope, Kke the 
VoriieeUa larva, Miiller; their e^s seemed to be much smaller 
and more spherical, interspersed among the larger ova. On the 
6th Novembtf , still more ^gs bad been laid, and new animals 
excluded ; the numbers of the VorticeUa larva had much dimi- 
niiJied. On the 6th, many more animals seemed to have been 
excluded, but no new eggs had been laid. The Vort. larva had 
almost entirely disappeared from the infusion. On the 8th, the 
number of animalcules remaining was comparatively small. It 
continued nearly stationary to the 11th, tm which day no new 
eggs were found on the sides of the vessel, although the dark 
spot (ovarium) beade the intestinal canal, was very distinct. 
On the SOth November very few individuals remained, and no 
new eggs had been laid. 

With regard to the size of the animal, my observations are 
not quite in accordance with those of Ehrenberg. In his table, 
he states it at from J™ to ^"'. I usually found them larger; 
the largest individuals were very commonly \"', some almost 
J™, more exactly j^"'. The ova could be detected with the 
naked eye, when tbe glass was held up to the light, like small 
dark points adhering to its sides ; and my eye is capable of dts- 
tinguishing objects of the size of j'g"', when close to the eye, 
and in active motion like the infusoria. With a lens magmfy- 
ing three times, the eggs appeared like small disks, and tbe 
empty sacks could be distinctly perceived adhering to the sides 
of the glass. Under the microscope, their ^zes varied from 
^j^'" to go'", without, however, their magnitude appearing to 
depend upon their internal developm«it; for I found ripe etn. 
bryos both in the small and large ova. Their form was geue- 
i-ally oval, approaching more or less to a drde. Their colour 
was often dark, yellowish-brown, and opaque ; some were par-

tially of a ii^tw colosr, partiouUriy. at the maighiB ; others 
throaghout of a lighter o^ur. No trace of motion was t^ifier- 
Table in the dark. ones, v4ule in the latter the embryo .oftea 
made vigorniu movements, wid the ciliie w»e seen distinctly 
wibrabng in the interior of the ^g. The fonu^ were therefore 
evidently die least developed ova. We may ttmvfore pertu^ 
form th^ following scale of their devek^imeDt : 

1. The dark opaque ova I reckon the most unripe ; they 
VBiy in size, and are more or leas elongated. Wh»i praised 
btiween platai of mica, the granular homt^^eneous-lookuig sub- 
stance' in the interitu- is dischai^ed (the yolk), and the en^y 
transparent envelope remuns (the cIkkioo). I could never ob- 
serve' any thing more than this granular substance, .and itaoHi- 
taining membrane. I could never detect a second coat, the 
amnion of Bhrenbei^. The chorion had a remarkable t^ 
pearance, bc4ng beset with shtn^t, fine, dense hairs, resembling 
the closest fur. This hairy covering is very apt to escape no- 
tice. I did not observe it at first ; but, after having «noe seen 
it, I fbuiid it present in every case. This villous coverii^, 
which reminds us so closely of the chorion of the higher ani^ 
nuls, is most distinct in unbroken opaque ova. It is, however, 
vimble, though much less dirtinctly, when their contents aze dis- 
charged. This structure is the more interesting, as Meyer in- 
forms us (Okens Isis, 18:^8, p. 1285), that the envelope of the 
e^ (chorion) of the Alc^oneSa is beset with talice. Grant 
' found it on the ova of the sponge, and Carus views it as the 
niK^eus of the respiratory vessels or gills of the chorim. 

S. An ^g has sometimes an opaque nucleus and border, 
when the rest of the granular mass is transparent This also 
was beset with hain. I am not sure whether this is the second 
stage of the development or a dead ovum. 

3. The ova <^ this stage are much more transparent, filled 
with a browniih-yellow, granular substance (yolk) ; some spots 
are dariter, and resemble turbid flocci in the midst of the ovum. 
Stxne <n;ganization is discernible in the interior, but there is no 
(fistiiKt sepm-ation. of orgiuis. Some resemblance seems to exkt 
to the embryo of the common leed), where the first change per. 
ccptible in the gbbular ovum is the formation of cedls and ve- 
Mdes.

The amtaal emcuated the oonCents of its intestiDe by an anuq,

Uactioo of the veticntar organ seated belovr the organs of gene- 
ra^on, and which Ehrenberg views as the musculas fjaculator 
semviia. The smdl ova escaped most easily, the larger wema 
somewhat longer time of making their exit, and usually broke 
during the passage, and evacuated their granular contents. If 
the uterus was distinctly two-horned, as in Ehrenberg^s figure, 
each honi contained lour eggs, the lowest one was the largest 
(5^5"), most transparent at the edges, and with the dark granu- 
lar mass still in the interior. The three uppermost ^^ weK 
commonly oval, and had also a central darker nucleus. The 
ovarium thus contained simultaneously ova in ver^ different 
stages of development. 

Much nmilarity will be found to exist between these fri^ 
ments of a history of the development of a Hifdalina and' the 
tables which Cams has given of the Latinularia JltiviaHUt. 
Here the egg is formed of a chorion and tai albuminous mass 
(yolk), which forms the embryo. The rogatory organ here also 
moves in the egg, from which Carus concludes this oscillalion 
to be the respiratory act, whi(^ thus takes place in the fetus be- 
fore any nutrition can be cohcaved to take place by the moutb. 
I am also disposed to adbpt the same view't^ the rotatory oi^aa 
being theapparatus for respiration, but its complete estaUish- 
ment would require some connection to be traced between the 
reepirotory and the circulatory sysfems, and a more complete 
demtHistnrtian of the Existence df the latter than we us yet po^

III. Inleilitte, and Experiments on Nulrition with Carmine in some 
other Infusoria. 

Feeding by means of a soluUon of carmine, completely suc- 
c«cd«l with ine in the larger Infuscuia. In the smaller, sucfa 
as the Monads, Cydidium glaucoma, &c. &c. I could not re- 
peat Ehreoberg^B experiments, as I had not tbe means oS em- 
ploying sufiSdent magnifying powers, although the animals tbenw 
selves, even the little VUnio aceH were quite distinct under my 
microscope. In the Paramecium, TracheHut, Kerona, EupUea 
and Vortieelia, however, with a power of £0-60, their filling 
with red colouring matter was C|uite apparent. Ehrenberg re- 
commends for this purpose tbe pedunculated Vorticellae; but I 
could never succeed with them so well as with some of the 
others, probably because I never found the Vort. amvallaria so 
Jaige as Ehrenberg mentions in his table (s'l"')- I seldom found 
th^n to exceed ^n"', but here without feeding, I could distinctly 
fee the stomachs like round vesicles, and when filled with car- 
mine I counted tburteen. In tbe Eupl^a I counted twenty red 
points filled with carmine. But the experiment succeeded ia 
the most beautiful and perfect manner with a P(a'am€ecium, 
probably the cktysalis, which, on one oa:asion, I found of un- 
usual «ze, from I'" to ^'q'". The red-coloured sacks were 
^uite apparent with a power of S4, and very distinct with one 
oi 48. The animalcule' itself can ea^ly be seen with tbe naked 
eye. When the intestine is once filled, it remains for several 
days equally distinct. I therefore recommend this infusory ani- 
mal to any one who is deurous of examining their structure, 
aoi of exhibitiog it distinctly to others. 

Just aa little as Ehrenberg could I ev« succeed in indoaog

The remarkable VorHcella versatilis or Ophrydiunt veraat. Ehr. 
could never either be induced to take the colouring matter. I 
found this species in great numbers towards the end of October, 
fbrming gelatinous balls of an inch and a half in diameter; 
they were best adapted for experiment, when their ^ze was about 
iV". This wonderful animal is of a beautiful greea colour, 
paler, and more transparent near the edges : their interior con- 
sists of a granular matter, or of small round vesicles (?) 

IV. On the Change of Form, and the Succetsiont cf Injutorin in 
Infunon*. 
It appears very probable, from the observatious of Ehrenberg, 
that the genus Monaa, and several of the allied genera, are not 
distinct animal forms, but merely the young state of the Kolpo- 
da, ParamadOf &c., which are unable to reach maturity widi- 
out a division like the Rhizomorpha and Byaaus among the 
Fungi. This idea has been subsequently adopted by Dr Esbh- 
wdler. I have myself do continued observations on the primi- 
tive generation of the Infusoria, but for several summers the 
appearance mentioned by Eschweiler * has appeared to me very 
remarkable. I have seen monads and other small infusoria ap- 
pear in infusions which disappeared in a few days, and gave 
place to other genera. Thus the water above mentioned as 
containhig-the Hydaiina, on the seoond day after being taken 
^m the pool, formed a green crust on its surface, particularly 
near the margin of the glass in which it was kept. When I 
examined thb green mass with the microscope on the 23d Octo- 
ber, it swarmed with the Euglena viridis and Enchdyi pulvis- 
Ctdus, which swam about with much activity. Some of the first 
species were seen in the act of expiring, and others quite dfead. 
During this curious phenomenon the elongated form of the ani- 
mals was changed into a globular. They died in whole massei^ 
particularly near the margin of the vessel ; the gre^ dust Uien 
forming the so-cfdied Priestley's matter, although it may arisfr

S^ Dr WagDeT on the Stna^ure and 

as veil from other green Infusoria. Anothu- animalcule seen 
in considerable quantity was the Volvoa! giobator of different 
sizes. On the S7th October the green mass df dead inftlsotia 
was stilt present, and formed a pulverulent Itjrer on the'^deof 
the glass turned towBrds the Ught. On the surface there was a 
pellicle which exhibited numbers of the Kerone pustulata of ^"' 
m size. Some bad a transverse fissure, as figured by Ehren- 
bCTg; and there were a few examples of Vorticella larva, Mul- 
ler. On the 3d November, not only the Evgkna, but also 
the Kerone pustj^afa, bad entirely disappeared. A new set of 
organisms had sprung up ; the dead Euglentx still retained thrir 
green colour and rounded form, aud lay on the sides of the 
glass; many of the green masses, however, had become brown 
and yellow, and had aggregated together. Here and there I saw 
a ParamtBcium, and more commonly the Vorticella larva, the 
interior cS which was filled with dead Euglenx. There were 
also a few of the Hydatina senta. The VnrtkeUa larva gra- 
dually disappeared as the Hydatina increased ; and the latter at 
last vanished, so that, on the 10th November, the water was 
quite destitute of infusoria. Similar successions, though not in 
■ the particular order of this example, I have seen on different 
occasions. At other times I have observed several infusoria co- 
temporaneously existing together, as the Monas, Vorticel^ 
Trackeliug, Kolpoda, Kerone, ParanuEaum, all of which disap- 
peared at once. Certainly these transient swarms of living be- 
ings within the compass of a ungle glass, is an object of very 
great interest. We are quite ignorant of its cause. At first 
sight it might aeem to favour the idea of the generatw equivoca, 
but my belief in this hypothesis has been pretty well shaken by 
Ehrenberg''s numerous observations, as well as by the few which 
I have been able to institute in the course of a single summer. 
Nowhere in nature do we see any animal arrive at once at its 
perfect state ; there is always a sort of dormant state previous 
to their properly independent existence. , The invisible ani- 
mating power of the Creator every where in animated nature aU 
taches itself to the state of the egg, and at this state of existence 
more especially, does he seem to breathe into living beings tbe 
breath of fife. The dorfnant state of the ovum seems to be the 
tranution from the empire of mind to that of matter. The old 



Devdopment <^tbe In^iuoria. S53 

maxitn " Ompe.viTum ex ovo," is for me, aa well as Ebren- 
betg, equally bLadJng upon the infusorial tribes. I certain]/ 
think .it very, possible that there may be a generatio equivaca of 
^gs, but not of perfect animals ; but our data are aa yet quite 
insuflideat for the demonttration of the question. 

V. On the supposed Connection betteeen the Vegetable and Animal 

It is very commonly an admitted fact, that vegetables and 
animals touch one another in their lower degrees — that they ev^ 
pa^ into each other, — that not only in one genus do we find 
both animals and plants, therefore species from the two king- 
doms of nature which can be separated by no generic distinc- 
tion, but that even a plant often produces an animal which, du- 
ring its growth, again changes into a plant. I must admit that 
these notions were once very attractive to me ; that the globi^les 
of the blood were simple monads, which were formed from the 
living animal matter, like the infusoria from dead animal mat- 
ter; that the Ectosperma produced monads which disappeared 
after t^e short life of an hoiir, and grew up to Confervse. I 
not merely believed dm myself, but have publicly taught it aa 
an acknowledged fact, till I took the microscope in my hand and 
experimented for myself I have now perhaps fallen into the 
other extreme; fw, certainly, I have never succeeded in obser- 
ving the separation of the globules of the blood from the paren- 
chyma, alUiough I do not pretend to deny its possibility ; nor 
have ] at any time seen how animals change into plants ; and, 
notwithstanding Spallanzani^s often repeated experiments, doubt 
■very much of the resurrection of Furcularia after having been 
dried up for more than a year. When Treviranus, Bory St 
Vincent, and others, have seen globules issue from the tubes of 
the Confervse and swim freely about like infusory animalcules ; 
when Edwards has seen ConfervEe again spring from these 
globules after settling; when XJnger and others have seen ac- 
tive globules, which he calls Monads, issue from the £ctaaper- 
ma clavata ; I do riot doubt the fact of globules having issued 
from these crjptogamic plants, which sprung about in different 
"directions : theise motions seem voluntary, therefore they are ani- 
mals'; they are very small and roundi therefore they aremo<

nad*. Here, therefore, a moving globule and s mcmad are ood^ 
■idercd as identically the same. In order, hovever, to establish 
tlui, they should have been seen to take in colotiring matt^, 
and to contain internal cavities, which Ehrenberg has done with 
i^ard to all the true mmads. Ingenhous, Treviranus, Mocns- 
chuch and Nees VoniEsenbeck, if I mistake not, have said that 
the Priestley's matter consists of dead infusoria, and that from 
this congealed vegetable mass, as it is called, Confervse, Ulvw, 
Tremelke, nay even the Hypnum riparia, have all been formed. 
Here I do not doubt the fact ; times without number have I seen 
the Priestley's matter take its origin from green iafusoria, sudi 
as the Englena viridis, and the green pellicle in pools and iu- 
fusions very generally consists of the dead bodies of infusoria, 
but never have I seen plants formed from this green matter; 
it continued long fresh, and became afterwards yellow, brows, 
run together, and fell to the bottom. When Confervte grew 
in the infusion, or in the midst of these masses, there was never 
a tntnmtion between the dead infusoria and the living f^ants. 
Whether these plants arose'from the spontaneous developideflt 
of globules, or from the presence of infinitely smell seeds in the 
water when drawn, I will not pretend to determine. StiU less 
can I believe in the observations of Wiegmann, that the En- 
tomoatracif Cyprij and Cyclops are generated in putrid water 
from Priestley's matter, and after their death are changed into 
confervte. He even asserts that he has seen confervte springing 
out of the feet and antennae. It is very possible that these ani- 
mals have arisen on confervte, but not^^wm them. 

VI. Structure ^ the Cercaria. 
The exact observations and inimitable drawings which have 
been given of the Cercariie by Nitsch, must be known to every 
one who has occupied himself with researches into the infusoria. 
Subsequently Baer has made some higlily important observa- 
tions on their formation, after Bojanus had called our attenutm 
to the subject During last summer I had an opportunity of 
observing the living Cercaria; in some water which had been 
drawn from a pool for the purpose of examining the infusoria, 
and which had been at rest in a glass. It contained also many

plaoOTbe*, and a» I think the PI. catinattu. On e x am in in g tlie 
water in a few days, I observed with the naked eje Bome very 
active animalcules, which I immediately recogaifled as canatw 
by their vtry rapid motions. Their numbers iocreaied on tl^e 
fbUowing daye. My observations were afterwards interrupted. 
On dmer ezaminatJoQ the ammal appeared to be the Cercaria 
Zemno, Muller (Eacyclop. Method. Fl. 8. Eg. 8. IS.), a E^ecies 
which, as NitBch supposes, is probably identical with the Cararia 
ma;or (Beytr. but Infusorienkunde, Tab. ii. fig. 1-8,)^ for it re. 
aemUes it exactly ; only I oou|d detect none of the fine hairs m 
the tail, which, however, only appeared to Nitsch with veiy 
high powera, and with the Geld of vision half illuminated- I 
employed a power of 4:8. For a long time I was quite de. 
lighted with the singular movem^u of these Cercariie, but X 
turned my attention principally to their internal structure, which 
is not sufficiently known. 

The cercaiia which I observed was about J'" in length. The 
tul and the body were nearly of the same thickness ; the latter 
was longitudiD^Uy striated. The substance of the animal wm 
bomogeneouE, transparent, and of a milk<white colour. At 
the anterior extremity was the round extensile <^Ding of the 
mouth, from which it appears to be surrounded with a wreath 
which, was notched. This mouth is succeeded by a smaller 
very distinct oesophagus, between which and the mouth the in- 
testinal canal seemed to be somewhat narrowed, I saw no 
trace of the forked organ noticed by both Nitsch and Baa- ; not 
was the course of the intestinal canal here marked by any dark 
spot, but it appeared to me merely to resemble a broad band 
extending Jrom the mouth to the anus. The ovaria were very 
conspicuous, placed on the two sides of the body. When the 
animal was moderately extended, they made several convolutiona 
in the form of an S, from the two sides of the oesoph^us to the 
cloaca. The convolutions were less distinct vhen'^he animal 
was much extended. The hinder extremity was very short and 
broad, where the ovaria formed two irregular masses. Thar 
texture appeared granular, and had a beautiful appearance, 
th«r dark colour being contrasted with the transparency of the 
rest of the body. Their exit into the cloaca I could not dis- 
tinguish. Their origin towards the anterior part of the body

was very distinct by two dark spots. Nitsch took these spots 
ft* eyes, whidi they certainly are not, Imt th* ongiD (Jf ncit the 
exit, against which, however, we have all analr^) of the 
ovarii, which are here destitute of the granular tissue.' Tliese 
spots sometimes assumed a spiral, sometimes a Tot^ced or double 
forked, form. With regard to the organs of motion, the month 
is large, more or less extensile, and surrounded with a notched 
or plain'margin or ring ; it is bell-shaped, and is attached to tlie 
body by a narrow pedicel. The tail has lateral itideritatfon^ 
and longitudinal strise or fibres towards its middle. I am in- 
clined to suppose a union of transverse and longitudinal fibres, 
true muscular tissue, for I am convinced that these animals pos- 
sess muscles quite analogous to those of the higher animals, and 
Ehrenberg has demonstrated it with regard to the hydaliha. 
How the tail is fixed to the body, I have not been able ftd 
dsely to determine, but it is probable that a sort of pTrdonga^ 
tion is fixed into a notch in the hinder part of the U-utik. 

These few observations on the iorusoria cannot be compared 
with those of Nitsch, Baer, and Ehrenberg; they are onlyk 
fragment towards the completion of the history' of tkia vaW 
kingdom of nature. In conclu^oa, I must add a word to ex- 
plain why I have taken no notice oftwb recent observers of in- 
flisoria — Bory St Vincent and Muncke ; but so triuch do I vfilue 
the labours of O. P. MuUer and Schrank, that loweitlo'tfUtfJ 
to assert that I consider the communications of the format' ai 
quite lost for science. When Muncke says that he hrt'd deVot^ 
from three to four hours every day for three weeks ' to the t^ 
Bervations which were laid before the meeting of Natli^tstb '^f 
Hamburg, we can only lament that a man of acknowledgt^S re- 
putation as a natural phttosopher has spent so much' time' tlSei 
lessly upon matters irith which he was quite unacquainted. It 
Is worse with Bory; for it is quite incomprehetisible hotv any 
man can be considered as a naturalist of Cminenee, whb •dvii 
plays in his writings an inaccuracy, superficiafity, and igiiotatice', 
that must be frightful to every orie w'ho examin^'closely his 
works, and As revolting as the frivolity of which liis Hlstbir^

inherent magnetism cannot be altered, yet an «cdn awj tttO^

the smallest dej^ee diminishing Uie (mpaai pbwer of the 'ttc^

the northern and southern polarities, each portion, insttad of 
comprising one quality only, will be found to be a distinct laa^

Induction is that welt known property of n^inets,' of pro- 
ducing in contiguous ferruginous substances the nkagnetic oon-

tion of any thing prevtotisly foreign to the ferm^Dous bodies, 
as nothing (as we have ^ewn) is abstracted from the inducii^ 
magnet, and nothing in reality infused into the iron thua magi- 
nedzed. Induced magnetism, therefere, may be de&Md,-J-<^

emfiojed as a satigTactory test of qu^ty in its Bcveral kinds. 

At sma]l dietancee fnxn a powerful magnet the inductive 
energy is very striking, and productive of a number of well 
koown and ioleretting pheoomcna. I.et a f»ece of soft iron, 
for instance, such as a common key, be placed near the extre- 
mity of a-bar-magnet, either in continuation of the eame line or 
inclined tp each other at any angle, provided either of the ex- 
tremities of the key and magnet are the parts nearest to each 
other, an(^ the key so placed will instantly acquire such a mag- 
netic condition as to be able to support anotber smaller key or 
otlierportionofiron St either of its extremities. And though the 
magnet be placed beneath the table, or under a slab of marble 
pr 4uy other solid substanoe, the induc^ve influence will be pre- 
cisely the same, so as the distance and portion of the masses 
are similar. 

Biit these pbeDomena, which have usually been observed only 
in ciFcumstances of juxtapositicKi, may be satisfactorily exhibited 
at^cbnrideFable distances, as shewn by the foHowing experiment, 

A pair of very fine bar-magnets, S feet in length, S^ inches 
is iM^adth,'. and j^tb (^ an iooh in thickness, being placed over 
each other, a quarter of an inch asunder, and with similar poles 
adjacent, were nnployed, with a view to their inductive effects, 
at different distances, <hi the nearest end of a soft, bar of square 
irso^ ISfMDches loagv and 1 indt in thickness. In order that 
tha induetive influence ought be separated from any magnetism 
of position derived from the earth, the iron bar was placed in 
tfad east aad west magnetic line, and in a horizontal position ; 
aad, that' the bumki delicate experimenta might not be affected 
by the magoetisai aocjuired under the toqk powerful influences^ 
the most' instant and weakest inductions were first tried, and 
each expecimait verified by taking the mean power of each eni 
o£ the bar alternately presented to the magnets. The iron bar 
thus situated (Platell. Fig. 1.) su6t4UDed, by the ^tremity

But these results, if ve consider the nature of the polarities 
induced in the bar and the suspended substance in their rela- 
tion to each <Mher, will be seen to be less than what might be 
obtained by umple induction at the respective distances. For, 
let the acting end of the magueta be the north pole, then the 
Diagnetism induced in the nearest end of the iron bar TviU be 
the contrary, or southern polarity ; but the tendency of the 
magneU on the end of the nail, or other suspended substance, 
in contact with the bar, will be to produce also southern pola- 
rity,— because of this end of the nail, under the circumstances, 
being nearer to the magnets than Uie lower end ; consequently, 
the induced m^netisms c^ the parts of contact of the bar &nd 
nail, being, as far as derived from the magnet, of the same kind, 
must have a tendency to diminish the acdou of the bar on the 
nail. 

' Id order to compensate this defect in the results, another 
sories of experiments was made with the same apparatus, id 
which the iron bar, whilst kept in the same vertical plane, Was 
raised on each trial so much above the level of thie magnets,— 
namely, one half the length of each suspended nail, — that the 
in6u»ce of the magnets upon the suspended body might be 
nmilfir at both its extremities, and consequently neutral. Un- 
dfr this arrangement (Plate II. Fig. 2.) the inductive power, 
HP had been antidpated, was much greater, so that the different 
substances were now suspended according to the distances in 
the li^t column of the, table.

arid Phenomena of Magnetic Induction, 261 

Whilst theae striking results were obtained bj tbc rcUod of 

tfae end of the bar nearest to the magoets, tbe influence at the 

distant end was but feeble — tuetaining only nulg of fO grmns, 

mid 37 grains, at the two last distauces of the third column. 

In exparinwots merdy illustrMive of tjte jnukt of inductioa, 
tbe arrangement of the last column of the table may be still 
farther improved by raising the bar so high that tbe lower ex- 
tremity of the suspended substance may be on the fame faori' 
zoDtal level aa tbe magnets. In this poution the lower extre- 
mity of ttie nail beug nearest to the magnets, becomes a south 
pole, with a north pole, by consequence, at the upper end, 
which, bein£ aUractable by the southern polarity induped in tbe 
bar, augments its suspensive power. And such was tbe increase 
obtained by experiment, that tbe nail of 482 -grains was now 
suspended (by either end of the bar, when presented in succes- 
sion to the magnet), at tbe distance of nine inches, and the key 
at the distance of 7.S inches, the inlerral between the bar and 
the .magnets. 

Subsequent experiments were made with a fiat iron bar, a 
quarter of an inch in thickness, but amilar in all its other di- 
mensions nnd qitality to tbe bar prenously employed. The 
distances of suspension obtained by this bar, indicated a smaller 
quantity of inductive influence, corresponding pretty nearly with 
its proportion of surface. 

These, however, are but proximate results : the inductive et 
feet as measured by the deviations produced on the needle of a 
compass was therefore resorted to for a more satisfactory ratla 

The apparatus employed in this investigation consisted of 
four similar bar-magnets, each 18J inches long, 1 inch broad, 
and ^th ofau inch, thick; the square bar of soft iron used in the 
foregoing experiments, being of the same length and breadth as 
the magnets; and a delicate compass of four inches diameter. 
The magnets were placed parallel to each other on a board, half 
an inch asunder, in order both that their combined influence 
might be employed for affording more decisive results, and that 
they might be presented at diflerent distances from the bar In the 
same relative poatlon and equality of magnetic power. Tht irOB 
bar was place<I in a horizontal position, in the first iristaiice b^

magnetic direction, There, bdng in the plane of the magnetic 
equator, it was free from any disturbing influence from terre*^ 
trial magnetism. The magnets were then placed at various 
successive distances in the line of the bar, according to ihe ar- 
rangement represented in Fl. II. Fig. 3. The distance of the 
bar from the compass, which throughout the series of experi- 
ments was always precisely the same, was 5| indies, and the 
distance of the magnets from the bar was first 12 inches, and 
then at equal successive intervals, as far as four fert. The ob^ 
ject of STong upon intervals o( \it inches was,- beeause tb«t dis- 
tance was very nearly ihejbcal length of the magnets, or the 
lengUi betwixt the two fod w caitres of attraction in either half 
of the magnets, to which the wbc4e of the varying magoetic'in- 
fluences, in such segm^its, might be referred. The empli>y- 
ment of intervals, therefore, of focal lengths of the magnet and 
iron bar, was calculated to simplify the investigation, and taaf- 
ford more satisfactory results. Though I had a mouve for fix- 
ing upon the portion given to the iron bar, the distance of iu 
focal pcdnt from the centre of the compass bring about one-half 
of Its focal length ; yet, whilst its position was, on every trial, 
always the same, the particular distance was of httle importance 
In this position of the liar, the first situation of the magnets 
was (6 J + ISj + 12) = 81 inches from the centre of the con(- 
pass ; tbe second 43 ; the third' 55 ; and the fourth 67 inches. 
Placing now the magnets, in the general line, with their south 
poles directed towards the east, at the shortest interval, tbe bar not 
being yet placed intermediately, the power of the magnets alone, 
as determined by tbeii action on the needle of the compass, was 
first observed, and found to be 2T 42". The iron-bar, the mag- 
netism of which had been carefully neutralized, was then inler- 
posed in its asugned position (according to Fig. 8.), each end 
of tbe bar being alternately presented towards the compass, 
when the mean deviation, by adouble set of careful observations^ 
proved to be 38° S^'. The unassisted action of the magnets 
was then verified by another trial after the bar was removed, 
and found to be unaltered ; consequently the increase of devia- 
tion of (38° SJ' — 2r 42") = 10^ 21i', indicated the proportion 
of action due to the magnetism induced, under the particular 
drcumstances, into ^e bar <^ iron ; or rather, (baag directly in-

Now, ^nce a magnetic force or forces of variable intensity, 
acting upon a compass needle in a direction at right angles to 
terrestrial magnetism (as in the foregoing experiment), will pro- 
duce deviations the tangents of which will be proportional to 
the actual intennties ; the tangents of the angles of deviation, as 
above determined, will aSbrd a measure of the relative forces 
acting upon the needle in the several positions of the magnets 
and iron-bar ; whilst the differences of the tangents of deviations 
will indicate the quantity and proportion of magnetbm induced 
and developed in the end nearest the compass, at the several di^ 
tanc^ of one, two, three, and four feet. Were the magnetism 
induced upon one end of a soft iron-bar exhibited, as if by A 
perfect conductor, to the other end, then would these diAerenc^s 
exhibit the actual effects of induction; and the lawofindiictioti, 
as to distance, might be experimentally determined. But this, 
as will hereafter be shewn, appears not to be the case. There- 
fore the differences iiidicative of the actual induction at tbe rt 
mote end of tKe liar are probably not proportional to the relil 
live forces known to be acting upon ihe end nearest to the mag-

bets. Stffl, hoverer, the di&ratices of Ijie tai^Mits in^tlib fNW-

at the several distances of 1, % fl, and 4 lengths. \ 

Whilst the foregoing experiment affords an indicatiim of t^e 
relative force of ma^ietic inductitHi at di^rent distances, a|>- 
proximating the knowa law of direct attraction and repulsion, jn 
which the forces are inversely proportional to the Equaree of tfie 
distance ; it likewise shows the facility with which the magne^c 
energy induced at one end of a bar of soft iron is conveyed to the 
other. There was nothing in the experiment, however, which 
could afford any data for ascertfuning whether the transmiesi^ 
of the magnetic energy from end to end of the bar was perfeot ; , 
or, if not, what proportion of reustance there might be in a bar 
of sol) inm to liie free commuivcation of induced magnetism to 
the remote end of the bar. 

With the view of obtaining information on this point, I pro- 
ceeded to vary the experiment, by ascertaining the deviations 
, produced by ilte tame end of the iron-liar as that on which the 
influence of the magnets was immediately acting; and this was 
accomplished hy the following, arrangement. 

With the four magnets pUced on a tray, exactly as in (he 
former series of experiments, their inductive influence aa the bar 
of soft iron was now examined, when arranged after the maAJier 
represented in Fig. 4. . ^ : 

The compass, in this case, being betwixt the magp^tg.and the 
iron, was placed, as in the former experiment, at the distance of 
5j inches from the bar ; and the intervals were now measured 
across the oHupass, aod noted at 1, S, 3, and 4 feet, as bt^ore. 
Under this wrangement, the south poles of the magnets being 
presented towards the compass, caused the deviation of its north 
pole, as before, to be towards the west ; and this deviation, on 
the applicatitH) of the iron-bar, was augmepted,.. because the

Another mode of experimeoting, hosever, which subaequriotly 
occurred to roe, is nincb more practical, satisfaetory and lurful, 
afibrding, by direct experimeDt, the actual quaotity of mpgnt-

padty, in reference to the energy of the indumg m^net iteelf, 
blether with the exact proporticai of influence prodoeetl on each 
at any g^ven distance. 

The arrangement, in this case, which was peculiarly smfie, 
reqidnd only this adaptation, that the bars of iron or steel used 
far trying the quantity of ioduction should be cf the same 
length, or neariy of the saine length, as Uie magnet employed. 
And when comparative experimoilB were made on the relative 
cspacaties of dif^rent kinds of iron and steel, or iron and steet 
(tf different tempers or degrees of tuurdneia, it further required 
0a order to obtain at once direct and final results) that each bar 
should be of the same dimensions as the ma^^et ssade use ai. 

Fig. fi. Plate II. represents this new arrangement. M is a . 
magnet [Jaced in the direction of the east or west point of the 
oompau C at m^ distance,— say at tvojbcal lengths from the 
centre of the compass, when the deviation by either pole is carc^ 
fuUy observed. An iron bar, I, of the same dimensionG as th> 
magnet, is thep placed exactly over it, separated by two little 
blodcs of wood, or other substances of equal thickness, adapted

BeaauKof this quality that the magnetic influenas, I coii»d»,

may be applied. For liiere seems to be a particular relation be- 
tween the ducuUty of iron, and its capacity for magnetism— 
the soDest and moat ductile iron having the greatest capacity 
for the magnetic influence. Hence it is considered, that the 
experimental determination of the capadiy of different speci- 
mens <^ iron by the method adopted in the last experiment, 
might (as already su^ested) aSbrd a simple anif decided test 
and measure of their relative quality and value in commerce. 

For this purpose a bar-magnet of modCTate dimensions (say 
of IS inches in length) and a small compass would be ^ the 
apparatus requisite. The different spedmens of iron, whose 
proportionate quality as to ductility is to be determined, might 
require to be forged into the shape and uze of the magnet, or 
at any rate into a similar shape and size with each other, and 
then softened equally by being moderately heated and allowed 
to cool slowly in the same place, or under similar circumstances. 
The magnet being then placed in the east or west directicm of 
the compass, say at two lengths distance, will indicate, by the 
deviation of the needle, its own power of attraction, which, being 
observed, one of the specimens of iron is laid exactly over the 
top of the magnet separated by two small blocks of wood, or 
other substance of equal thickness, and then the deviaticm pro- 
duced by both extremities of the iron-bar alternately observed. 
(See Fig, 6.) The difference between the mean of these devia- 
tions and that of the magnet alone, will serve as a measure of 
the capacity of that particular specimen for induced magnetism. 
Whilst the compass and magnet remain undisturbed, the rest 
of the specimens can be brought successively to the test, being 
always kept at equal distances from the magnet by the same in- 
terposed substances, when the comparison of the measures of 
their different capadties for induced magnetism will, if the theory 
be correct, afford a certun indication of their relative qualities. 

With a view of assisting me in verifying this theory, my frigid 
lEdward Roscoe, Esq. of Liverpool, kindly furnished m^witti 
Kveral characteristic specimens of the different qualities of iron 
most commonly manufactured in Britain. Though the examina- 
tion of these did not enable me to discriminate small difllerences, 
yet, when the common and best qualities were compared, the 
magnetic capacity of the latter proved to be nearly one>tenth 
irreater than any of the common kinds. ,-- .

FLUBHCB, AND PhBNOHKNAOF. MaONKTIC INDUCTION. 

Sect. 1. Q^de Nahm ifMagiutie Induction. 

Magnetic InductJoD, some of the laws of which have now 
been examined, b of most extensive infiuence in the sdence of 
magnetism, being more or less engaged as an agent in almost bU 
its phenomena. The attraction of femiginous bodies, not hav- 
ing previous polarity, by the magnet, depends simply on their 
inductive capacity, — the proximate end <^ the magnet first'de- 
veloping a polarity different from its own, and then, according 
to the general law of both magnetism and electricity, attracting 
the contrary polarity thus developed. In whatever subttance, 
therefore, magnetism can be induced, there will be a capability 
of being attracted by the magnet, the degree of attraction btaag 
proportionate to the inductive capacity. It is also the generd 
influence by which polarity is developed in bodies citable of 
permanent magnetism. 

Though we have no means of explaining the essential nature 
of an agent so subtle and extraordinary as that of magnetismi ' 
yet we may exhibit, by striking experiments, n variety of its 
properties and phenomena. The connection of the magnetie - 
princi|de with iron is, as we have said, inherent and inalienable, 
and the two denominations or polarities appear to have perma- 
nent residence in each ferruginous particle, being mobile in the 
particles but not separable from them. 

Ferruginous bodies are usually and naturally devoid of any 
strong magnetic energy, the arrangement of the magnetisms €( 
the different particles being such as in a great measure to nen- 
tralize each other. But the mere proximity of a magnet, or 
even an electrical influence, as has been shown, disturbs the na- 
tural equilibrium of the polarities, and tends to arrange thtm by 
its inductive energy in a magnetic series; 

The development of the magnetic condition in a bar of iron, 
then, is the mere arrangement of the inherent polarities in a 
magnetic series, which arrangement appears to be the result of 
two influences, — the direct inducUve influence of the proximate

The pn^rtion of energy of the magnetism directly induced 
on the different portions, and that transmitted from portion to 
portion, it must be observed, affords no measure of the relation 
between the two influences in an actual bar of iron, because 
there the number of the particles, and the intimacy of their 
connection, renders the transmitted energy by far more conffl- 
derable in sc^t iron than the direct influence. 

SacT. 2. —On the Inductive Effects of the Magnet on Iron. 
The experiments detailed in the preceding parts of this essay 
are all illustrative of these effects ; hut, being designed for the 
examination of the laws and nature of induction, they haye been 
Umited in their character to tliat particular class which seemed 
the best Calculated for the attainment of these objects. This 
section of the essay, however, not being confined to any particu- 
lar investigation, will admit of all such original experiments as 
may serve to illustrate any of the various influences and pheno- 
mena of this interesting property of the magnet. 

Sebies a. 
With ft «ui^ bar-joagnet, or with Wo or more equal bars 
placed over each other in parallel juxtaposilioD, and vritb 
similar poles ocMiodent. 
As these experiments are the more striking, in proportion to 
the pow^ of the magnets, it is advisable, if the baii^ be well tem- 
pered, so as not to injure each other by thnr proximity, lo em- 
ploy at least a pair of magnets, according to the arrangement of 
fig. 1. before ^ven. The original experiments were made with 
a pair of threei-feet magnets : but nearly the -whole series can be 
exhibited, though with less striking effects, with a pair of good 
-twelv&inch bars.

Experiment 1. — For the Suspen^on of Iron BaUs. 

These balk consist of the best soft iron, and require to be 
turned in s lathe sud well pt^lished. A convenient size is i^gths 
of im iQcb iiT diameter, weighing about 70 grains. Of this de- 
eoriptigfi sixty to eighty l»lls will be requisite, and from twenty 
u> tturtvi of smftller dimeasions, in a graduated series. . 
■ The suspensjiin of the balls in a single dependent chain ot 
connexion, is a satisfactory means of trying the power of the 
magqets. A pair of good twelve-inch magnets will suspend 
«bQUt 9x equal balls of seventy grains weight, — perhaps eight 
!or nine, if gradually reduced in size towards the bottom ; whilst 
my three-feet magnets will sustain do leas than fifteen equal 
balls, or eighteen diminishing in size, in a single series. Here 
we have a beautiful illustration of the imiictlve power of the 
magnet, assisted by the inductive influence of each ball upon 
the otie contiguous to it in the series. The polarity of the first 
of tbe chain is developed directly by the action of the magnets, 
but the second is at once influenced by the first hail and by the 
magnet, and so on throughout the seiies. 

The balls, when employed without any other apparatus, may 
lie attached by the magnetic influence in a number of pleasing 
fonss, OS festoons, fringes, and bunches of grapes. 

But I proceed to describe some more novel arrangements. 

Experiment i.--^For the Suapentum ^ BaUa at ^ 0a:lremiiie$ 
if Crooked Wiret. 
(1.)— Fig. 7. represents a modification of the experiment 
with the balls, which has a very plea^ng effect. For this expe- 
riment two pieces of iron-wire, about 3 inches long, and }th in 
diameter, bem into the foroi represented at &, and notched into 
each otlw, are' added. . Bdng ctnawd at the notched part, and 
Aliachad to the pole of the three-feet magnets, eat^ extrecoity of 
the Hires .w;^ BUEtain eleven or twelve equal balls. The sub- 
atanaa betw^ra the wir^ and the mf^eta js so <rf>loDg piece of 
polished iron, by the int^^ntiQn of which the i^ect of the ex- 
.pmiaent is improved, th<H]gh the number of balls ct^iable of 
being .euspetided is diminished. It may. be necessary to observe, 
once for all, that the points of contact of all thesuhstancet em- 



and Phenomena ^ Magnetic Induction. 1IH9 

ployed in these expenneats should be highly polished, and, to 
obtain the best effects, the iron of which they are composed 
should be annealed or softened previous to the polishing. 

(3 >— Fig. 8. a, PI. III. exhibits another modifltfttion oT the 
experiraeol, in which a half link of iron-wire, b, fomilar to tbt 
former in thickness and quality, is appended to each extreAii^ 
of the crossed wires, and the bolls are' now suspended fVom efeirf 
point. Each of these, at^out the interposed iron, will soUm 
from two to ten or more balls, according td the poWtff of' the 
magnets. 

(3.) — An cl^ant variety in this experiment is obtainedj rai- 
der powerful magnets, by adding to the half links guspenied from 
the cross wires, a second half link to the £xtrethity of «ch of 
the first series; and, even at this distance from the nT4gsets,'li 
chain of hx graduated balls (see Fig. 9.), may be sitspendtd 
from each of the sixteen downward termioatioDsof the last ^lies 
of wires. 

But these three last experiments admit, of course, of an u^ 
mited variety of modifications. 

Experiment 3. — Forvuition ^Chahu <^- ffaJf JAnla. . 

A 'p«r of good twelve-inch magnets will susttdo a diian of 
about six half links, of the size of wire above described,' which 
may be increased to five full links, measuring above nine indies 
in length, by the use of the three-feet magnets. Fig. 10, a. 

Tbi* exp^iment is modified, as represented at ^i by the in> 
terposiuon of a ball between esc}) complete link ; at c, by a ball 
at eadi limb of the half links ; at d, by the introduction of 
the, crooked wire. Fig. 7. 6, Sec. ; and at e, by a weight of cork 
suspended from the fourth complete link.

This is a very striking and curious experiment. Fig. 11. -o, 
represents the general arrangement. A T^ Gtde key held 
down to the table by a piece of fine thread, or a hair, is brought 
within a smtJl distance of the extremity of the magnets, wb^e,

weighing fiSO grains, has been supported by my own three-feet

The story of the suspension of Mahomet^s coffin within a 
loa^totie cave is amusingly illustrated by this experiment. 



With a compound horse-shoe magnet and an iron-bar, or single 

' bar-magnet, for partially neutralizing one of its poles. 

All the experiments of the preceding series can be equally 
well |)f"rformed wfth a good compound horse-shoe magnet, ac- 
cordlrig'to the arrangement represented in Pi. IV. Fig. 18. 

The magnet being suspended from a frame of wood, ia so ad- 
justed iri height that one of its poles should rest upon a large 
flat bar of iron, or else upon the end of a bar-magnet with op- 
posite Qoles coincident. By this means the pole in contact with 
the flat bar is partially neutralized, so that the operation of the 
unattached pole is left more free and unembarrassed for the per- 
formance of the eTTperimente. 

It is not necessary to r^at here the series of experiments . 
with this app^atus, being precisely similar to those under the 
prece<Kng arrangement ";'

With two equal bar-magnets, placed over each other at a few

As in all the experiments of the flrst series, the tnaguAisn in. 
duced on the different masses of iron was chiefly upon the ^or^ 
tioiu Q^arest to the magnets, the influence on the opposite ex- 
tremity of each portion bein^ merely consequential, it occufrsd - 
to me, that if the substances employed in the experimests «Ert

Jd^thnal Obtervatiens on the Station of Citric and Nitrout 
Aadi to Bromine and Iodine. By Aathqb Cohmii-l, Eaq. 
F.R.S.E., &C. Counnunicated by the Author. 

Xh a Iat£ notice, mention vtas made of some upsuccessful at. 
t«npts to oxidate bromine by meiuiB of nitric aud, by a process 
ajaiUr to that which effected the conversion c^ iodine into iodic 
acid*. :It was farther stated, that when a small quantity of 
hrotoiae was binled with nitric acid for a considerahle time in a 
long tube, the upper and open extremity ctf which was bent and 
terminated in water, and tlie intermediate port kept cool by 
moistened bibulous paper, so as to condense the bromine as 
it (oblimed, and cause it to fall "hack into the add, the water, 
alter the free bromine which bad passed over was expelled by 
heat, g^ve with nitrate of silver . s pretty plentiful precipitate of 
bromide of silver. This preci[ntat« I have ranee found, from 
dD.ex^aupauna of the Hqiiid in a variety of nays, was caused by 
^e. presence of hydrobromic md.; and the question arose, to 
what cause the occurrence of that acid could be attributed. To 
Hsoertaip whether bromine was capable of decomposing pure 
yater by similar treati;neDt, and of so giving rise to the forma> 
tjon of hydcobrumic add, a little bromjoe was boiled with wat«^ 
under the same circiunstanices ; but after the liguids .employe^ 
liad bqw deprived of oolour by a gratle heat, so hydrohrpniic 
aff4 PMild be discovered by the agency of chlorio^ and subse- 
qiient i^tation with ether. It ixcuvac neceagary, therefor^ to 
Jgqk for. some third body, which, by ii« atGnity for oxygen^ m^ 
fxmtribmte to the decompositiDii of w^r ; and as a coloured ai^ 
^D^iig nUiric add had been employed, U appeared probatiW 
that nitrous add might have that e&ct i^fcprdingly, on 0% 
king the experiment with colourless nitric add and bEomin^ 
and afterwards driving off free hroDune from &.e trster, in 
. which the extremity of the apparatus tenaioated, by a gentle 
beat, no hydrobromic acid could be observed in it, when ex- 
amined by means of chlorine and ether. On the other faahd, 
whm the experiment was repeated with a red and highly fiim- 
ii^ nitric acid, the presence of hydrobromic add in tbf water

S81 Mr Connell on the Kelatwn of 

was made abundantly manifest by the same reagents. A Tike 
r^ult was bbtmned, when an ccid was employed which had been 
highly charged with nitrous acid, by passing throu^ it a cur- 
rent of deutoxide of azote. 

From these experiments, it seems to follow that, under the 
inSuence of bromine and nitrous acid, a portion of water is ^ 
composed by long continued boiling, hydrobrorok acid, and 
prolwbly nitric acid, being formed. This resuU is somewhat re^ 
markable, because, under ordinary drcumstances, nitric and 
hydrobromic adds mutually decompose one another. It does 
not appear that all the bromine employed becomes hydrobromic 
acid, a part of it being usually volatilized. 

As it would appear that the precautions necessary for dnui- 
niahing the loss of iodine in the preparation of iodic add by the 
action of nitric acid have not been well understood •, I Ulink H 
prt^ier to add the following particulars, willingly leaving W 
others the determination of the comparative merits of the differ- 
ent metiiods which have been proposed for the preparation of 
iodic add. 

The essence (^ the method by nitric add, consists in using a 
vess^iif very large capadty in relation to the quantity t^ mate- 
rials employed. I would recommend that it should be capable 
of containing forty or fifty times the quantity of nitric add ac< 
tually used. The reasons obviously are, to afford a large ia- 
torual surface on which the iodine volatilized may be condoised, 
and from whicb it may be wa^ed back agun into the ftdd, and 
to ^minBh the quantity of acid-vapour escapog by the ttetk, 
which ought to be as narrow as poinble'f-. A very strong add 
ought also to be employed, and the boiling is best maintained 
by the smaH flame of a spirit-lamp, to as to prevent, as much ia 
pos»b1e, the heatingof the sides of the vessel. Operating in th^ 
way, although I have always experienced some loss of iodine> yet 
I do not OMicdve that, with due care, the lo«s is so gt«at as

Nitrk and Nitrous Jcids to Bromine and Iodine. SSS 
CoDStitute a serious objection to the method *. There are few 
dieoiical processes which are not att^ded vrith some sacrifice of 
materials ; and it seems a m^ter of very little consequence on 
what material that loss falls, provided the total expense, in com- 
parison with other methods, is not increased. Indeed, plana 
might easily be devised, by which all the iodine whicb escapes 
oxidation might be condensed, and saved for another operation. 
And if it be objected that the process of ebullition is tedious^ I 
shall leave to others to determine wheth» more time and trouble 
ate expended, than in the numerous steps of other methods. 

It will give me much pleasure, if the su^estton of M. Serul- 
He, whose recent loss science deplores, shall be found to facili- 
tate the process ; but in the only experiment which I have made 
on the subject, I could not observe that the employment of an 
acid, whidi had been highly chai^^ with nitrous add, by pass* 
ii^ through it a current of deutoxjde of azote, offered greater, 
advantages.

slow progressed drilizaiion, of the cultiTstion of tbearKoBd 
sdences, and of the general difl^ision of nscAit knowledge.' A 
eonqueror did oo^sionally arise, infiamed w'ltA amUlioD, and 
actuated by' an - entfiuaasm for conquest, who ctinied in bis 
arm; men poBsessinga knowledge of all the stience 4^ the-age 
in which they lived. When a Greek 6r Roman g^n^rai 'had 
conquered a kingdom or a province, thefirstcareof acooqiiarw 
generally was, to introduce among the inliatntaAta a knowledge 
of the arts then known ; and to this cauie many of die andent 
£ur(^>ean nations owe the introduction of the first raya of intel- 
ligence by which they were enlightened. To retain p6s»easien 
of conquests Ekdy to be refcovered by former rulers fironl iitt^- 
tine commotions, or loss by the sudden ineiir«oii^ of ndgblxxir- 
ing tribes, a ready communicatiDn from one place to anotba*, 
and a rapid march of troops to quell any occasional insurrection, 
or hostile attack, would form the first objects of the conqueror's 
solicitude. Hence arose the Roman roads all over Europe, and 
particularly in Britain, where traces of their remans yet traverse 
the island from one extrenuty nearly to the other. If, in the 
course of these roads, a large river crossed its directioo, which in 
floods was impassable by troops, then a magnificent bridge was 
generally erected. There were thus constructed numerous 
bndgea in the course of a Roman itinerary. These have been (^ 
great advantage, even in modern limes, by affitrding faculties of 
communication that would otherwise have beoi unattainable. 
The methods of selecting lines, and of laying out of road^ have 
been lately much in^rbved ; therefore, the points where formerly 
bridges had been erected, have been found to beinjudidous; 
and, cDBsequailly, in countries where manu&ctures- and oom- 
nierce have beeti introduced, it has b«en foond indi^iebaaUe to 
change the' line of direction, and tO selfert new sitei'ftfr' Wdges ; 
though, in those countries' that liave slightlychariged iheir col^

in several of the noet ancieot temples of Greece, but Dothii^ of 
the kind is to be found in any of the ancient moDUfseots of Per- 
aia «* E^pt. Moat of the apftrtments of tbe ruim of andent 
^E^ypt are covered with a single stone ; and, in the gaUeries of 
the pyramids, of which the roofs oomist of numerous pieces, 
thur peculiar coostructiao readers it hij^ly probaUe that the 
boilder was i^orant of tbe arcb. The Greeks seemj therefore, 
entitled to the honour of tbe invention. The arched dome, 
however, appears to have been invented by the Romans, in 
tbe later monuments of Italy, tbe Etruscan dome, find tbe Gre- 
cian temple are combined, aa in tbe famous Faotbeon, even.in 
its most ancient form. 

In modem times, mathematical and mechanical principles 
bave been applied to the investigation of the properties of 
bridge^ X)r Hook proposed tbe inverted catenary as the .best 
form of airarcfa, in which all the strains would balance one an* 
other. This curve may be applied to most cases that occur, 
though it has seldom or never been used in practice. The cir- 
.cular arch has been, from tbe simplicity of its construction, most 
generally introduced. Of late years, however, the elliptical 
arch, from its convenience in keeping the crown of the bridge 
low to suit the level of the road, and its superior elegance, has 
been much employed. When the semiellipse forms the arch, 
this curve rises more rapidly at the haunches than the semicir- 
cular, of the same span, and thus, besides the advantage of be- 
ing lower at the crown, the under part of the arch forming the 
voussws^is bj.tb^t m^Simuch more capacious, and conso- 
guenlly better fitted to adinit a tree passage of the water id

meats perform^ bj Du Buat, the following laws were dte«>- 

vered: 

1. Id small velocities, the velocity at the surface exceeds that 
at the hottom in a very considerable ratia 

5. This ratio diminish^ in proportion as the velocity of the 
current increases ; and, in very great velodties, approaches near- 
ly to a ratio of equality. 

3. Neither the magnitude of the bed, nor the slope of Ae 
river^ changes this proportion when the mean velocity remtdns 
the same. 

4. When the velocity at the surface is constant, that at tho 
bottom is constant also, whatever be the depth of water; or t]ie 
inagnitude of the section. 

6. The mean velocity is an arithmetical mean between t&at 
at the surface'and that at the bottom. '" 

It is very difficult to determine the velocity at the botU)tt&1)y 
^periment ; and the proportion between it and the former cRitai- 
ni^es as the mean velocity increases. Du Buat determined "diis 
variation by experiment, and thence deduced the foHottteg 
rule. To 6nd the bottom and mean velodties when that nt the 
surface is Imown, take unity from the square root of the surfiice 
velocity, expressed in inches, and the square of the remainder is 
the velocity at the bottom. Half the sum of these two wHl ^ve 
the mean velocity. 

Ex. If the surface velocity in the. middle of ihe current^ be 
S5 inches per second, what is the bottom and meab velocity i* 
^m. V26 — 1 = 5—1 = 4, and l'' 1= 16 Ae bo«tom. vdodty ; 
therefore, g — ■ = 20J the mean velocity. As the meani ve- 
locity is most generally required, it may be found by the follow- 
ing rule. From the observed mtr/ace veioei^, in the tiihi^ qT 
the stream, increoied by I, suitract the square root ofj^ aur- 
JiKt vthc^, ihe remainder wUi be the -m^tu^-.vsiof^. _^ the 
whole aectttm. From the same cKample ax befonv •^k'f^miil^ 
= 25i — - 5 = £0^, the mean velocity obtained more readily 
than by the former rule. 

This discovery w of great importance, because the veloiaty of 
the surface, in the middle of the stream, is easily mea<ur«4r. from 



Military Biri^et, and the Patuige of Rivera. 291 
wliMi* bjr this rule, the mean Till be leadily obuined ; and it is 
the mean velocity that must be used in calcul&ting the diachargc^ 
supply, force, and every other effect of running witter. 

Several experiments are resorted to for the purpose of deter- 
mining the niean velocity of running water, such as a cylindrical 
rod of wood, loaded at the lower extremity with a piece of lead, or 
straight glass tubes, having their bottocas filled with small sbtrt^ 
to beep them perpendicularly in the water, and at such a de^th 
as may suit the depth of the stream. In absence of thoe, 
weeds or shrubs, having a proper quantity of earth adhering to. 
th«r roots, may be conveniently substituted, when great pred- 
sioD is not required. By using a Bufiicient quantity of these at 
different points in the breadth of a stream, the mean velocity vS 
the whole flowing mass of water may be obtuned with consider- 
able accuracy, fiy observing the mean time in seconds by a 
good watch, or half or quarter seconds pendulum, the volume 
of water that flows through a given space or distance in a given 
limp, may be accurately computed, which may be turned to 
conuderable advantage in many philosophical inquiries*. 

Fron a vast mass of experiments, Du Buat proceeds to de- 
duce an empirical formula, on the principles that have now been 
detailed, and at last arrives «t the following expression for the 
mean velocifyf ^rwimng water, ia French inche8,pertecnnd^ 

In which V denotes the mean velocity of the water in French 
inches, r the radius of the section, and b the distance, divided 
by the fall in the same measure, that is, if the fall be two feet 

in a mile, then ^^ = ^^^ = ^, and therefore b = S640. 

By r, or the radius of the section, is meant (he area of the 
Uwuverse section of the river in square inches, divided by the 
linear surface of the water in contact with its banks. Or it may

tiie size of the river, their existence is doubtful, the trial should be made 
Bdmewhere between anj two sInuodtiES, not &r distant from each other." 

To perforin this, it may in general be remarked, that the 
bank diould be first entered at about one-third the length of 
t^e reach, supposed moderate, not exceeding half a mile or a 
mile, below the first unuosity or convex turn of the bank, and 
oti^t to be turned slanting downwards towards the opposite 
convex bank, as much above it as the entrance was below the 
first. 

A Thus cToielng obliquely the transit of the current from ride to side, both 
e^ttcMnee vtU be avoided, and I have frequently found rivers fbrdable in thii 
manner, which could not be crossed at an^ point perpeadlcukrlj. The Spa. 
nirit«ra7 wtth wUchl served fbided the Esla, in th« campaign of 181^. 
without loss or difficulty, bj taking advantage of this circumstance; and in 
the same manner I forded the Douro near Zamon, and several other formi- 
dable rivers." 

The author terminates the first section with many similar ju- 
didous remarks on the passage of livers. 

' The second tection of the tmA is devoted to the properties 
of the pontoon, and to the manner of laying a pontoon bridge. 
A pontooHj it is well known, is a portable boat, conveyed on an 
appropriate carnage from one place to another, along with ao 
army. When a sufBdent number of these boats, with, their ap- 
purtenances, can be carried with a given number of soldius, 
they serve the purpose of constructing a bridge over any unford- 
able river in the course ot their march. In the British service, 
the ponlocxis are generally made of tin, supported by a proper 
frame. There are two kinds uEually made for oar service. The 
larger-sized pontoon weighs about 9 cwt. The appurtenances,

cirt. ; makh^ the whde 85 cwt. The ranaller, widi ita appiuv 

tenances, weighs only about 27 cwt*. 

The author gives accurate practical rules for determining the 
d^hs to which either of the pontoons in oqr service will sbk 
in water when loaded with a given waght, and also conversely, 
to find the weight of load corresponding to a given depth. From 
these, a table is added, showing at once, by inspection, the 
depths corteapondiag to given weights, which must prove ver^ 
useful to ipeTsons not conversant with intricate calculations, or 
when an eitimate of these must be made (juickly for any special 
purpose. The method of using this table (page 38), is exem- 
plified by applications to infantry, cavalry, and guns. 

" The comparative powers of the two kindi cf pontomi," th* autbor mUs, 
(page 43), " are exhibited in the preceding paget; from whui itappeanlhat, 
with the BBme wei^t of in&ntrj, the small pontoon is immersed 4 inches 
more than the other; and not being so deep b; 31 inches, the guniralei ai« 
then taHy S^ Inches above the water. ' Terht^ the adopUon of a medfwn 
tize, aa the only nature of a pontiMn, woald ba pit&raUe." 

The author then states the equipment of a full trmn of 36 
pcHitoons, in four divisions, but which our limits will not admit 
us to subj(nn. 

In page 48, the method of laying a pontoon bridge isvei^ 
fully explained, and methods of detennining the distance of the 
opposite banks of a river clearly illustrated. The author tbrows 
the investigation of some of his practical rules into notes at the 
bottom of the page where they occur, and by this does not in- 
terrupt the narrative. It would have been an advantage to 
have given a formula and rule for the trigonometrical operation 
also, though this may, in his opiaioH, be supposed to be. derived 
^m works on trigonometry. In some of these that are re«Uy 
adapted to practical men, a convenient rule or fonnula may he 
found, though most of our ordinary treatises ustidly ttu^t in 
schools are remarkably deficient in these particuiaia,; VknlBl. 
lowing rule would have been convenient for th{8i]Hir|ua& ,.'.ji! 

• To lender thew: Ba& ftom the tWtcta of shot piercing their sides, it Wcyild 
be very convenient to hare the interior cavity subdivided by tin tr^Terses, so 
that, though even one or two of the intermediate Bpaces were Me3ltWli Wa- 
ter, still the pontoon would not sink. To prtvent the pontMiM' fflBig.wlth 
water, a taipanling or canraM dect might be placed on mich of then as were 
moot liable to such accidents.

falls without, and the logarithm of the measured base AB; the 
sum of these, rejecting tens in the index, will be the It^nrithm 
of CD, the perpendicular breadth of the river. We have.beoi 
thus minute in this particular, because, if the breadth of a riv«r 
is' not accurately known over which a pontoon brii%e is to bi 
thrown, the capture of a place, or the loss of an army, may b« 
the consequence. 

" This vaa abundantly proved in the paaeage of the Oaronue at Qreatia, 
In 1814, bj tbe army of the Duke of WeOingtoa, previous lo thebattieof 
Tovlouse. That city serred the eoemy as a double lite de pmi. Ita andeut 
wdls were in a very defeocible state, on both banks of the rivei ; and the 
comraunlotian between these two works was kept up by a good stone-bridge. 
The ^habltantl of the country had been employed, for some time previous 
'(•tlldt period, la npalmigand sbcngthening the andent ramparts, and in 
mounting the cannon on them. Two attempts had been nude, a few 6iiy» 
before ilM at Grenade, to pass the river above Toulouse. The first, at a 
place called Portel, &iled for want of a sulfidnt number of pontoons to reach 
' across ; there being still about 36 yards of river remaining after they wczc ^ 
placed in the line. Tliia &ilure arose from not having correctly ascaiained 
ttie width of the river at the place racommmded for efiecting the passage." 

This liiowa in a remarkable manner the neeesnty of deter- 
mining the breadth of a river with pre4»«6n. 
" The seated attonpt was made at St lUqiws, a town situated on the 
- toetny'shaiJk ThaopflcatJonb^aoatduefc. Aparty ofaboutfiftyin&ntiy

(Mcount of tfte prvrldus Tains, and the ttwps were ordered to utum to tbe

'It was next determined to pass the river below the city. 
The bbttMn here, as well as at St Boques, proved gravelly, and ■ 
none c^ the Bochors would hold. The cables next the left bank 
were, therefore, secured to trees; those next the right bank, at 
the suggestion of the Duke Of Wellit^ttMi, were made feat to 
, anchors buried on shore. These, and many other interestftig

it has been withdrawn, in both smalt and large rivers, is treated 
at full length, so aa to be easily understbod by engineers eni- 
ployed in .these services. Our author next illustrates his dif-

The fourth section of the work is occupied with the raethjiMjg 
of constructing Flying Bridges, and employing them for th« 
peosagB of troopa across unfordable rivers Sir Howard Dout 
^las^ves teveral of tbe moet convenient and effective modes of 
erecting the necessary apparatus for this purpose. The flyiag- 
bridge i« farmed by anchoring a floating body, such as a buoy 
-m or near tbe ocntre of a river, so that a bo^ attached to it bf 
■a cable or dnin may ieo«ve tbe action of tbe stream obliijuely. 
By this meuis a force is derived from tbe current, which moves 
the Vetsal across the river. The manceuvre will be n^Qre^as^y 
executed widi a tomewhat long cable than with, a sb^^vne- 
In great rivers, sudi as the. Rhine or tbe Danube, two lai^ge 
boats or vessels are ootninoDty used. On tbe sides ot these, pa- 
rapets of timber, wool, sand-bags. Sic. may be «pnstructed, as 
-was practised by Charles XII. in )m passage of the Duna in 
-1701' The adtbor, after having giving complete infpnuaticw 
on tbe methods of eonxtructrng and DHuaagiog flying-bridges,

dition to the method of constructing rafts, a variety of uwful 
rules for finding the contents of beams, and valuable tables rela- 
tive to- their contents- and specific gravity, are subjoined. An 
article on gua|^Dg, or determining the cajMcily of casks, in or- 
der to obtain their buoyancy, is likewise recorded. Inflated bags, 
made bfthe skins of animals, were even suggested by the Rbodian 
to XaOophon, to enable, him to pass the Tigris ; and Alexander 
hadrecounetotbismotbod iDtHxlertopasstheOxus. JUvytellB 
US that some of Hannibal's Spanish infantry passed the Bbone 
by Swimming, with the asastaace of inflate leathern bags, and 
Csesar informs us, that the Spoiiish light infantry prMtised tkm 
method of fjaasing rivers, as is at this day employed on the Tfc. 
gris and Euphrates. Canvass-bagR,-laakered over with s.sctla- ' 
tion of caoutchouc (Indian rubber), have lately been pn^osedi 
and in India, basket-boats, covered with undressed hides, are of- 
ten employed. In short, the extent and variety of informatitm 
relative to these more temporary expedients can only be duly 
appreciated by those employed in such operations, to whom the 
examples will prove invaluable. 

Our attention is next directed in section sixth to Carriage 
Bridges and Suspension-Bridges. Carriage-bridges are sup- 
ported on four-wheeled carriages, and are found to be very us^ 
ful in expeditiously forming temporary bridges in small shallow 
rivers and canals. Sir Howard does not rwommend the.Poni> 
vdant of the Aide Mimoire, a French book similar to his 
own, but therB is no doubt that the ordinary carts and waggoqs 
of a country may be sometimes found very useful for such pur- 
poses. A (^rriage-bridge far ii^utry, two-aWaaat, was madfi 
across the Douro, between Toitlesillas and Toro with U»e 
spring-waggons of'the army. 1^ bottom of the river was faaid 
^td even; the average depth being from three to four feet. 
The wagons were placed laagitadiniQly, at-distanpes fluit«d ^^ 
the lengths of the planks that bad been collected -for fioorii^, 
which were laid from waggon to wa^^n, th& -twl ^anti fcont 
boards being taken out. The same thing nay be done with the

the vtJume, and cannot fail to be liigfaly useful and instructive

with an analysis of its contents. To this is subjoined a valuable 
^pendix, on the strength of timber and other materials, of great 
importance to all descriptions of practical men, of atber Ae 
civil or military professions. 

We now terminate our examinaticn of this most useful and 
interesting volume, with Segur^g graphic description of the pas- 
sage of the Berenna by the French army under Napoleon, in 
his disastrous retreat from Russia in 1812; and the andwr's

flects upon the verj extensive, important, and elaborate attributes of the 
Cerp* upon which such services as these depend, can doubt the expediency of 
preserviDg such a nucleus of it as may insure the retention at little cost, of 
what has been acquired in a long series (^arduous and expensive training on 
actual service." 

' To these striking and fomble remarks, which carry oonvic- 
don to every mind capable of just refledjon, little need be added 
by us to recommend the protection of our seminaries to public 

' notice. If we allow our scientific institutions, either naval or 
inilitary, to be injured or suppressed, we may venture to pre- 
dict that the country will pay dearly for the sacrifice. Euler 

' and BougHer were honoured and rewarded for their theoretical 

'- ntvestigationB of the principles which should be observed in 
shipbuilding and naval equipments, and ^eir e^rts have been 
long apparent in the superior qualities of the vessels in the 
Fi'^ch marine. Before the establishment of our naval and 
iniliEaiy coll^^, their engineers were equally superior to ours, 
though they were perhaps inferior towards the close irf the late 
war. It remains with the government of the country to deter- 
mine what must be our future status as engineers "in either

the common difference, ninety-six being the difference in degrees 
between the extreme temperatures : the same operation b^ng

the difference J0^8 (the difference in lengths) should be eif^ty-

To apply these results to the case in quesdon, let us suppoie 
two coping-stones, of five running feet each, to be laid in mi^ 
sammer, when ihey have a temperature of Q^" Fahrenheit; in 
winter their temperature may safely be assumed at zero, m^ that 
the total variation of temperature will be 96*; and if we ^pose 
these stones to contract toward their centres, which would be the 
most favourable supposition as regards the tightness of the 
joints where a number of these stones are used, the whole length 
of stone put in motion by a change of teinperature would be 
live feet. If the coping be of granite, tbe distance by whi^h 
the ends of the stooes would be separated, in consequence o^ 
one degree's variation, would be sixty inches, multiplied intij 
.00000482S ^ .0002893;'and for a variation of 96 degrees, this 
distance becomes .0002895 x 96 = .097792 indi, giving a crack

476MmitiQiM an SaUtu Cr^aUiaation. By Hehbv OookV, 
. - M. D., Extraordinary Member of the Royal Medical Society 
of Sdinbui^b, Comamaicated by the Authw. 

Xii crystallizing small quantities of saline substances, it hasfre* 

3uent1y occurred to me to observe, that coDcentrated warm soVi- 
ons may. b« cooled down to the ordinary' temperature of the 
ajtmoEphere, without depositing crystals. This property, ibb 
^pertaining to sulphate of soda, is noticed in most of the sys- 
tematic works on chenpstry; but it is usually stated that JtJs 
qecessary to defend the solution from the pressure oi the 9tn)o- 
^here, by removing the vessel containing it from tiia Sire* whilst 

'" '\ Mifttfl "f '^^'l>|l't'"", """^ iininw<iatpl y ffirlfing it ^ln. 

Gay-Lussac*, however, has shewn, that atmospheric pressure 
does not necessarily induce crystallization ; be found that if tho 
liquid was covered with a film of oil of turpentine, it might be 
cooled without crystallizing. And more lately, FrofesstH' Tur- 
ner-f- has succeeded in the same experiment, without the use of 
oil, ", by causing the air of the flask to communicate with the 
atmosphere by means of a moderately narrow tube. 

I have made a number of experiments on this subject, witli 
many different salts; but I have never observed any relation to 
exist between the pressure of the atmosphere and thf occurrence 
of crystallization in supersaturated scJutions. The solutions 
have been cooled in vessels of ^1 forms, from a narrow-necked 
flask, corked or not corked, to an open jar, or even a wide basing 
without their crystallizing. 



'810 Ur C^dea on SaUw CtyttdiBjiation. 

Id other eaaes; ftben the solutioB has been' {tfaserrflcl ^Nin 

atmospheric prewure, the experhneot has aeTerthy«te<'failin}^ 
and die lait has crystallized. It requires some ddiracy to v»a* 
duct the experimeRt successfully, and mere protection frMn dM 
Btmospbers is no aeeurity agBiiut its Mting. And when it'saD< 
eeeda, and a supersaturated Bolutioa isthtn captained in aWsAii 
cloead flask tx phial, I have TouBd it as easily excAtcd faMnFystak- 
lize by.ogitaiion without removhig the cork, as wheQ-it !^ 'aos^ 
buned in an open vessel. 

Atmospheric pressure, then, I do not consider as a co»dtt)<m 
at all facilitating crystaliizaticw in a supersaturated solution. 
Nor bare I been able to determine what cmcKtMHiB ar6' Decessaii 
ry. CrystallitatioQ often oocurs without any cAvkms cttnae. 
The slightest agitation will sometinies produce it; even tbatoc- 
caaoned by stepping across the room has appeared sufficient 
Sometimes, ^ain, the solution will bear to be briskly agitated 
several times d^ly, for many successive days, without rt-yst^-' 
^ng. A crystal of the same salt as that in solution wilt gene-' 
rally bring pn crystallization, when placed in contact with the' 
Squid ; frequently, however, it fails to do so. As a gene^' 
rule, the stronger tfae solution is, the mor£ readily it ia excited' 
to crystallize by either of these means. ' 

Sulphate of soda is the salt most frequently quoted as pos- 
sessing the property of resisting crystallization ; but it Is t^ no' 
means confined to it, or to any genus of salts in particular, aiKa- 
line, earthy, or metallic. Yet there are many salts of which I' 
' hav^ never been able to form supersaturated solutions ; ' If tftere^ 
was the slightest excess over the quantity soluble in cdd water,' 
it was invariably deposited on cooKng,' however carefully khe' 
expnimeiit wast conduct^], and whether dr not t^e'solutStfn was' 
protected from atmospfceric pressure.' . To' this peciJiikHty I' 

sbalt aiihsequently revert. ■ ' 

In stating that crystalllzition Is qdlte indepetldeiit of a&no-' 
spheric pressure, I do not advance it as a new aiicdvery'i (mi" 
Mtheo- as a point requiring additional investigation. ' Thelear.' 
liest mention I find of it, is in Gay-Lussac's paper pubfished lil 
1819; but be seems to'have considered' some protec^oA neces- 
sary, and employed for this purpose a stmtum tjf cat of turpen- 
tine. Guy.Lossac also fomed RupetBHtwUvd adtUiMtS' with

Ip mention. These, as well as the £rst, will be suffioently ex- 
plained by the following desultory experimeots. It is necessary 
to premise, that, in all cases, tbe solutions were unprotected 
from attnoapheric pressure, except vhae the contrary is express- 
ly stated. 

. 1. A bot B(dution of carbonate of soda nearly saturated, sad 
contained in a six-ounce phial, was allowed to slaiul in a bot- 
saniLbath until the whole was cooL Twenty-four hour* aftar- 
wards it was perfectly fluid, but being gently mored* it solidi- 
fied. 

' S. A strong solutioa of sulphate of soda was filtered whSst 
hot into two phials, one,of which was corked immediately, and- 
the other was left open. At the end of three hours, the ctxiteota 
of each nasained fluid, and each became si^ oa bmngagkatcd 

. 3. A strong Bolution<^ sulfate of soda was filtered whilst bot- 
into an open jar three inches in diameter. TveDty.£>ar houn 
afterwards, it remained perfectly iluid. A crystal of the nine 
salt being dn^ped into it, the whole stdidified in a few seconds.

made-to filter Aar wdutions fully Bsturaled, they immetliate-

'4. A gtKmg station x>f muriate of lime was ckMtid Up whilst

perimenters of the present day seem to hare fall^ little 'stiblrt, 
in their oftn imagination, of in reality seizing the ultimate ^#- 
mentE of IxxSes, and of reconstructing thbm at pleasure. 

Newtmi long ago taught as to believe diat the elements of 
«oIour were of tolerable magnitude. ' His words are, " Could 
the jwwer of the microsct^ be so increased as to represent ob- 
jects at a foot distance, magnified 600 or 600 times above wbat 
they appear to the naked eye, I imagine that We might discovu: 
K>me of the coarser elements which enter into the formation of 
colours ; and that, with a microscope which magnified SOO&or 
4000 times, we might recognise them all, even those which form 
the black colour.'' Supposing that Newton Ii^ correctly esti- 
' mated the natural power of human vision, his elementary parti- 
cles, as appears from the following observations, would, (or the 
red colour, not exceed s minuteness of judco"' '° diameter, be- 
tween which and yii^sg'", all coloured particles, not excepting 
the black, would be included*. But it is probable that Newton's 
estimate of the acuteoeas of vision is below the truth, when these 
elementary particles would become considerably larger. But, as 
has been already observed by Herschel, in his Optics, it must 
Dot be forgotten that Newton, made a marked disUnction be- 
tween the elements of colours and atoms, as well as later philo- 
sophers, allbough he does not expressly say so. In the above 
passage, Newton does not speak of atoms, but of colodrii^ par- 
ticles. — {Traiti SOpti^ie, 1704; lib. ii, part iii: Ed. Franc

The smalt magnitudes which have been required for the ex- 
plication of the phenomena of light upon the theory of undul&- 
tioD, are exactly enough determined by calculation, but they 
can only' be considered as hypothetical, not as really observable 
quantities, as the whole theofy, however great its probaUlkjr, 
still requires more complete demonstration. The smallest MUgth 
of a wave of light on this theory, calculated from the most fiiaci

BottDetian theory of generation would be overturned." , 

Eoelle also gives a peculiar chemical microscopic explanation, 
{Kastner'a ArcMv. f. NaturWtre, xii. 348, 1827.) He says: 
Zymom con^sts of microscopic glt^ules, and forms with Glyadine 
Celatin (p. S60.) Zymom is the substance from which the 
simplest oi^aoic forms are produced on the occurrence of fa- 
TouriA)le circumstances (p. 352.) The ^bules of milk and 
blood are zymom; gelatin, caseum, starch, sugar, &c, contain 
zymom, (p. S.^0.) Silica assumes first a vegetable stmctiire, 
and from the zymom formed from thence arises wnmal lif^^ 
(p. 358.) Vegetable matter can be immediatdy changed into 
an infuBory animal (p. 360.) In favourable circumstances, the 
different kinds of infusory animals can be fbnnetl from zymom 
(p. 358.) The first infusory animal, the lowest organic f<mnj^ 
is an animated zymom globule (p. S58.) Zymom may, in cer- 
tain ptHnts of view, be considered as an egg, (p. 360.) The 
yolk of egg ctHisists of zymom united with mucus, (p. 857.) 
These are not hypotheses but facts, (p. 361.) 

That the origin of many organisms is the effect of putrefac- 
tion or fermentation, and therefore a purely chemical {wocess, is 
a very old opinion, and therefore could not fail of being repro- 
duced in an improved form in modern times. Gruithuisen 
{GehlcTCa Journal der Pkysik, viii. 51 9> 1809) has characteri^ 
the formation of the smallest co^anic forms as a peculiar kind 
of fermentation, and spedfies, besides the vitious and acetota, 
the infiaorial fermentation as a source of organisation. For^ 
merly the autochthoniens were supposetl to have been formed 14 
this way, afterwards it was limited to insects, and the plants, 
produced during the process, but now insects and the lai^er. 
plants have been withdrawn irom this cat^ory. It baftsinoe. 
been extended a little to include the Infusoria and Fungi, on 
account of their difficulty of observation, but from' which, as ou^ . 
observations have shewn, it must be equally withdrawn. 

Berzeliu^, who notices the sul:^ect in his .classical Lehrhtuck 
der Cficmie, but does not giveany obserratioosof his oWn, con- 
siders as probable the fact mentioned by others, that deed ot^- 
nic matter, on being moistened with vrater, generates infusory.

animals; alid views Professor Horascfauch's idea as not' impro- 
bable, tliat the prima germina rerum, or infusoria, may be 
formed in different bodies, under certmn external inffuencei 
ta other respects be has followed MM. Dumas and Mlloe Ed- 
wards in the' doctrine of organic atoms ; and the inorganio 
atoms^ wbiA bavfe been of so much service to the doctrine of 
chemical proportions, by the simple process of addition and sub- 
traction, are more or less ideal unities, which will long contiiiue 
of the most decisive practical benefit to chemistry. 

Quite recently Mnncke of Heidelberg has observed the march 
dr organic bodies in infu^ons with a microscope of Ptossel, and 
has »-riTed at the result, that a passage of organized matter 
takes place from vegetable to animal life, and from animal to 
vegetable life— (/iJs, 1831, p. 1088.) 

I must state, in the first place, that the whole range of mj 
microscopic observations are completely opposed to the prevail- 
ing opinioh, that in fiisory animals or fungi can be produced by 
simply pouring water upon dead organic substances. It must 
be admitted that such appearances are deceiving; but when exa- 
mined minutely, sometimes one kind of infusory animals, some- 
times another, appear under the most similar modes of treat- 
ment, and I have never been able to obtain certain forms by 
Dieans of certain infusions, although this is stated in all the met- 
nuals, and has succeeded with all the earlier observers. Ao 
cording to my results there are certain forms, but few in num- 
bOT, and tfiese the most diffused, whose ova or individuals are 
found in every kind of fluid, even in those of what are reckoned 
the most poisonous parts of plants. Blainville (Diet, dea Soc.' 
Nai. Art. Zoophytes) has also arrived at the same opinion with 
regard to the generaiio equivoca frbnf his own observaHons. I 
bare often laboured in vain to produce, at will, a certain spei^ 
ctes of organic bodies in little gloss tubes, although in oth^ 
eontainihg the same water,' and situated in the same circum- 
ataoce^ ihey multipli^^th the utmost profusion.

as these come near to it, hence these have probably a' w»*«tb at 
ten or twenty feelers around the anterior moUth bjieHin^, as in 
the Monaa pulvisculus, and the other still larger mOnades. It 
15 probable that each of the stomachs which are filled in our 
experiments with colouring matter, contain more than one 
Atom; if each stomach contains three coloured atoms, this af- 
' fords a proof of the existence of red and dark Uue particles

If the same objects are calculated according to the smallest ani- 
mals we have observed, which are ggim of a line in m^nitude, 
and sometimes contain four coloured points in the hinder part 
of the body, these latter parts, which are no longer individual- 
ly distinguishable, even by a power of 800, but are distingtA^ied 
in the aggregate, have a magnitude of U^^q of a line^ ^

It presents a level platform, elevated about sixty feet above the

the (isual alluvium of the Gangetic provinces. The country 
Is fertile and highly cultivated, and impresses us with a favour-

flatiked by a bell of roclffi of the aeeon^iry dan, vhich stretdie* 
in a north-easterly direction from the anciettt city of Btana, 
situated on the south-westem portion of the dbtrict. This belt 
19 mterposed between the newo- strata joit allnded to, and the 
tfeeidedly primary formations of the Jeypoor and'Ajmeer terri- 
tories : its easteni Hmrt is marked by a low hill range, seen a tHuitt 
^tAnee to the westward of the dty of Bhurtpoor. 

The sandstone quarries which have for centuries supplied aH 
this portion of India with materials for building, are situated in 
the Bhurtpoor district, and, aS these are important, both in a 
statistical and geological point of view, I shall, in the first place, 
eommunicate what little information I have been endiled to 
collect relative to their natural history. 

Of the sandstones there are three varieties. No. 1-. k a cios^ 
grained argillaceous sandstone, more or less slaty; of a uniform 
dark red colour, so soft as to be scratched by the knife, and ap- 
parently composed of unall particks of quarts, ceneitted toger 
ther by a ferru^no-argiUaocous basis : minute scales of .mic*<are 
distributed through the mass, to which ciicumstaiice' it "fp*- 
rently owes its slaty texture. No. S. is also a close-grained ar- 
g^laceous »itdstoa& This is a very beuitirul varisty, its c^ 
Imir is dark red, speckled with wbUe spots, whidi are generally 
roundish, and vary &om an inch in dituoeter to the tiie of, fi 
pin's head. This rook is less schistOK than No. 1^ coatsns leaa 
mica, and, when slabs of it are properly cut and squared, boB, 
at a little distance, exactly the appearance of a fin? red pratv 
phyry. No. 3. is a rock umilor in ptnut of texture and f^po- 
■itioa to the last, but is of a uaifmn salmoiMolour, paiong into

pearaDce; and it is impossible not to regret that the Eglttth- 
coloured varieties had not come into genentl use at tea eaHHr 
period. To the employment of the red saodstcme there is asdU 
stronger objection. This rock seems but little capable of nest- 
ing the decomposing effects of the atmosphere ; hence it is diat 
so few of the edifices, for which Agra was oace bo famous, ntyw 
remun entire, and of the few which still survive, the majori^ 
are rajndly falling to decay. The splendid mausoleum of Altber 
St Secundra is likely soon to meet the fate of its fdlows ; while 
at every step we take we perceive the moat stupendous ruins of 
palaces, and courts, and gateways, which less than two cAntnries 
ago were the favourite haunts of the monarchs of Hindostaii. 
Id every climate this is a nio§t serious objection, but in a climate 
Uke India it is quite ioeunDountable. In, comparatively speak- 
ing, modem days, an Indian monardi, surrounded by a court 
more goi^eous than Europe ever witnessed, pronounced this 
capital the " first city in the world -t-," destined to be etemd! 
We may smile at the vanity of Jehanghir ; but let us Bot negldbt

taught us. A day must come, distant thou^ that day mAy be,

so conspicuous a place in the geoli^ of the southern boundajy 
of the valley of the Ganges and Jumna, appear to be continued 
on with but little interruption into the Bhurtpoor district, where 
they occafflonally ore found near the surface, though, generally 
■peaking, they are hid from view by the alluvia of the Gangetic

340 Mr Macritchie'B Metmrologieai Tablet, 

sesEon has been seen so low as C€° or 50^ at sunrise : but this 
coOhien only took place ins clear morning, after a &li of rain, 
ftr, when clouds made thdr afipeanmce, there was no di&bienoe 
between the temperature of the external atmosfrfKre and that of 
itte room, although it mi^t have amounted to 13^ or 14° on the 
■ptece^g morning at that time. The heavy dews that fall du- 
ring the night, at this season, in clear weather, give a chilliness 
to the succeeding unelouded mornings more sennble to the kA- 
ings than a much lower degree of cold in more nor^em cK- 
mates. ' The weather becomes warm in February ; and the hot 
vinds commence about the beginning of March, but seldom in 
eamett bntil the vcmal equinox, and continue until the setting 
hi of the ndny season in the first or sectmd week of June. 
The hottest month is May, and the heat increases in sultry 
oppresdon as the rains approach, until their actual presence 
abates its insupportable tyranny. The heat of the night com- 
monly exceeds that ri the day in closeness for nine months in the 
year; and the most pleasant part of the twenty-four hours is an 
hour or two before sun-rise. 

The rainy season in general sets in with heavy rain from 
the eafrtward, attended by severe thunder and lightning; the 
higher clouds^ motion having previously come round by showers 
from different quarters to the point agreeing with the wind on 
the surface. The heaviest rain falls in July, and lessMis in 
quan^y until the middle or end of September, when the r^ns 
usually take their leave with a Jhod from the east, in a similar 
^tyle to th«r commencement. 

iVo/or and lunar halo* are very frequent when the atmosphere 
becomes hazy imd slightly overcast, but without that effect up- 
on the coming weather expected in variable climates, excepting 
when it changes from dry to wet, and the contrary. Lmutr 
rainbows are not uncommon in stormy showery weather. I 'hud 
an opportunity of seeing three very perfect ones, in one instance 
so well 'defined as to appear double. ParlteliA, «ith bright ^pd^ 
on and around the halos, are of general occarrenCe in Uie mares- 
ImIh and mackerel formatiofl, which the tjonds so'oftcn ffisume 
in an Indian atmosphere. Edipses do not materi^y influence 
the weather : in 18S8, the great aolar ellipse erf" April was not 
'-ftloWedby any alteration, with the exception ■ofhappeoing near 



kept at Bancoordh during the yearn 1837-38. 341 
to a periodical change of season, when they hasten its approach, 
as has been before remarked to be the only influential attendant 
on those jAenomena. Eartltquakes are g^ierally attended wiUi 
a hazy atmoBphere, with small low modonless clouds, and the 
breeze m the-surface blowing irr^ularly in stnnig eddicif with 
calms inta^emng. 

It is in May and September that Cholera Morbus and other 
diseases previul most In the year 18S5, the rainy aeasan did 
not commence before the 19th of June, continued throughout 
very mild, and broke up in so light a manner as scarcely to be 
remarked at al). In consequence, the weather, for a month bc:- 
fore their setting in, and at their conclu^n, was unusually close 
and o}^ressive, although the temperature was not higher than 
that of oth^r years at the times in question. The cholera raged 
in C^utta in June, visiting the country here and there on that 
and the following months, and reached Bancoorah, among other 
places, in September, sweeping off a vast number of the nativ:es 
in its way. After continuing for a fortnight o^ three weeks in 
the town of Bancoorah with fatal effect, ahuost in every cose 
baffling the power of medicine, it all at once left the place and 
appeared in Chatna, a village about eight mile^.to the northward. 
In tliis manner it travels through the country in continued hot 
moist weather, carrying off great numbers oi the native po- 
pulation, and, I believe, in some instances talking one portion 
d a village, or even one oA^ of a street, leaving the rest. of 
the village untouched in its progress onv'Brd. In Calcutta, 
tbt! cholera is among the natives in the Black Town almoat at 
all saisrais^ the bff stuation of the city, and the cr<»rdei} and 
narrow streets of the native part of it, being exceedingly well 
suited to keep the disease from abating even during the coolest 
pattof the year. At this time Calcutta is almost daily visited 
with a deiise damp &>g hanging over the city and the Biver 
Hoogly in the morning aod evening. In May 1828,. the cho- 
l^a was not only mortal to the natives in that (nty, but there 
were mar^ numerous iosUncas of its proving &tal to Europeans 
there and m other parts <^ the country than former yeivs had 
exhiluted. This o^t have arisen from the unexampled heat 
of diat season. There cannot be a more impressive case of dis*

On the Graphite or Black-Lead of Ceylon. ~ 

tSzTEKAL years ago, splendid apedtneDs of graphite were pre- 
sented to me by one of my pupils, who brought tbem from the 
island of Ceylon, where, he informed me, the minerol occurs in 
masses vaiying in magnitude from the size <^ a nut to several 
inches in diameter, imbedded in gneiss. Mr J. Prinsep has . 
latdy, in Ae " G-leanings of Science" an interesting periodical 
pubUsbed at Calcutta, published the following analysis of one of 
thevaneties: Carbon 6S. 8, iron 5.4, silica Sl.O, alumina 9-S, lime 
. 0.2, magnesia 0.1, manganese a trace, and loss 1.2, = 100. Su»< 
pecting, from tjie lai^ proportion of eartliy impurity in this ana^ 
lysis, ihaa some of the matrix had remained mechanically mixed 
with the graphite, Mr Prinsep mode the folbwiag adtUtional 
analyses: 1. The graphite^ uncleaned, left, as above, iron and 
earth, per cent 37.S. % Rou^ly cleaned, left a reeodue per 
cent. 18.5. 3. Crystals selected with care, 6.0. 4. Another trial 
left the very small proportion of l.g. The two last residua 
did not entirdy dissolve in muriatic acid; indeed the former 
yielded O.S of silica on analysis. This statement is illustrative 
of the accuracy of Earsten^s view of the composition of gra- 
phite, namely, that it is a mere modification of carbon, and 
the iron and earths are accidentally mixed parts*. The gra- 
phite of the HimoU Mountains yielded to Mr Prinsep the 
ii^owing ingredients : Carbon 71.6, iron 5.0, silica 15.0, alu- 
mina, &C. 8.1= 100.0. The English graphite was found by 
Mr Prinsep to yield, hygrometric moisture S.7, carbon burnt 
off with difficulty 53.4, iron taken ,up by acid 7.9, earthy inb- 
purities 36.0=100.0. As this variety was. marked of *^sup9- 
rior quality," it follows that, chemically coBsidt^vd, it ig inferior 
to the kinds found in Ceylon and the Jlimalas. 

The Ceyloo graf^te, Mr Prinsep informs us,,. bos oqly b^ 
known commerdaUy for five at wx years ; ^ government had 
shipped small quantities of it to England by way qf trial,, and 
it answered so well, that they were induced to receive it, amongst 
other articles, in lieu of revenue, at a fixed valuation, when tbey 
were suddenly surprised at the quantity of this novel currei)cy 
B graphite iriU be found in one of tW 



Anat^tit of Indian, Ckinete, and New HoOand Co^. 34T 
ofiered in payneat A Urge hei^ wu thus accumulated ; and 
as the island rixHinds id tins voiiwral, «nd there are no padloeka 
upon Hbe minee, ai in Ciunberland, it might soon effectually de- 
strt^ the iDCMue of the B<»Towdide Company, if introduced 
lately into the English market. The natives of Ceylcm make 
no UK of it. 



Andiy$es ^ several Indian, Chinese, and Nea HoQand Coals. 
By J. PxiNSEP, Esq. Secretary to the Fhyncal Class of fhe 
Amtic Sodety of Calcutta. 

Xhe folloving table, published in the Calcutta Gleanings of 
Science, comprises the results of several aiudyses of Anatic and 
New Holland ccols. The fourth column, containing the waXat 
expelled, is kept distinct from the three -whicfa follow it, under 
the bead of ocHnposition, as it is usual to include all the volatile 
products tc^ether. Shocdd the water be looked upon as hygnt- 
metric, the per-centage of cwbon and ashes must be iocteaaed 
to obtain the true oomposition of the coal : thus the Baghelpur 
slate-coal, after deducting 10 per cent, ofvat^r, contmns

leao 
From the last column in the table, it will be seen how totally 
. unfit are most of the Indian coals for the purpose of making 
coke. The Burdwan coke, with the exception of one specimen, 
would contain nearly a quarter of its weight of eutfay impurity ; 
the SQhet would be sull worse ; the anthracite of Baghelpur 
would be nearly half earth; some of the mountun coal from 
Ava would yield a coke of better quality, but of very little den- 
sity. The Chinese glance-coal alonfe forms a remarkable ex- 
ception to this un&vourable conclusioa against dtientat coal, 
and deserves to rank at this head of the hst in respect to its pu- 
rity as a coke, although in specific gravity it does not come up 
to the character of the English fuel, neither has it the spongy 
texture which must contribute much to the glowing tfoitibustion 
of the latter. It will be remarked, that the ashy resdue on the 



348 Analyait ^Indian, Chinese, and New Holland CodU. 
analyus f^ Engliih coke (No. 2)> much exceed what lAtould 
have been exjjected from the compontion of the coal whence it 
was formed ; this may be explained by supposing that portitHis 
of the ashes, probably the alkaline ealts, are vi^tilized along 
with the gaseous matter, when suddenly decomposed at a high 
temperature; or that considerable variaUon exists ia the quality 
of the material charged in the oven. Whatever may be the 
cause, the same deterioration might be looked for in the coking 
of Indian coal, which would tend to lower them still more in 
scale .of comparison.

On the Fo«»il Flora. 



1. MX fact that we do not know more th&n a f^ hundred Bpeci^s 
of fossil plants, shews the impossibility of our preteodiog at 
present to form any very plausible estimate or conception of the 
nature of the antediluvian flora, and also the hazard of att^ropt- 
ing, from the dUappeorance of a few species, in proceeding from 
one formation to another, to determine the abundance or pau- 
city of faifiiliea or classes of plants. It is surpriung to ob- 
serve naturalists characterising botonically whole antediluvian 
epochs, when they possess, as in the case, fw extunple, of the 
second epoch, the period of fonnadon of the new red sandstone, 
a groiip of twenty miserable remains, as the whole of the dis- 
posable riches from which such a result is obtiuned. Tt ia evi- 
dent also that we cannot, from the present fossil T^;etable re- 
mains of single families, form any satisfactory inference as to the 
number of their species, because it may have depended in part 
on acddent, or some unknown circumstances, that in one family 
many spedes and individuals are preserved, while in another 
but few remaius are met with. In other cases the circumstances, 
although easily understood, are not attended to, and the num- 
ber of fossil species found in the deposit, are coo»dered as the 
fuU measure of what has been destroyed. Thus in the first 
epoch two mosses only, but sixty-four lycopodis, are enume- 
rated ; but this circumstance does not prove that mosses and 
lyoopodi» formerly existed in the proportion of 3 to 64 ; for it 
is very natural that gigandc lycopodium stems would more easily 
reast the storms of time than the d warf moss ; and although we : 
Ob that account have only two mosses remaining from tbatpe- ' 
T^, it does not follow that they have not been more than ten [ 
tvries more numerous than the lycopodia. ; | 

It is ddubtful if botanists can determine with accuracy even 
the tasBoiy of the fossil specnes. Many of the remains at present 
considered as Lycopodiums, may prove to be Fems, or even ■■ 
Pines, the Sel^njtes excepted. Many of the gigantic, so called 
Equiseta, resemble tree-like grasses. The Marsileacese of the 
fmncr world may have be1ong(tl to the feme. The Vottnia 
has not yet been proved to belong to the Coniferse, and as the

\A Edinburgh on the SStfa of July, and proceeded dire^ly to 
KirktoD, Ck)Ta. Wer^ouned there till the 7th of August, when 
put returned to Forfar, while the rest went to GAea lala, and 
theice we proceeded aa the 9th acran the mountains directly to 
the station of Corex FtAKi, at the head of 6)en Callader, and 
paaang down the glen, reached CastletowD. Ho^ our short but 
most intereatiDg excursioo tenoiiiated : I was obliged to set off fur 
Edinburgh early next monuDg. Our fratune in regard of wea- 
tberwas thevery reverse of that of the party which had preceded 
us. It was hot, calm, and, without an exception worth noticing, 
fair. We were therefore enabled lo adhere to our resolution to 
devote almost our whole time to visiting new ^ound ; and the 
<»ily old stations which we went to were Loch Brandy ; the 
birch trees at the top of Glen Dole ; the rocks on which the 
A^ragaUit alpintu, the Oxytropi* campestrit, and the Cares 
Vahm severally grow. Among the fruits of this restduticm ex- 
hibited in the following list, I would particularly point to a fro- 
fusioo of Lychnis alpma, not seen before, except by Mr Dc»i ; 
to five new stations for Sonchut alpinui; to abundance of Gen- 
tiana tmtali», never before found in Britain, excepting on Ben 
Lawiers, and there only sparingly, and at long intervals, by two 
or three lucky botanists ^ to Thlatpi aipestre, new to Scotland: 
to the frequency of Sialaxit paiudoBa, in various stations ; and 
to Carex rariflora, gathered to satiety iu all the bogs at a par- 
ticular elevation od (rae range of mountains, thou^, before this 
season, two stations only were known for it. These discoveries 
are accompanied with a conuderation which multiplies many 
times the pleasure which I derive from them. The late inde- 
fatigable Mr Don of Forfar, by his unceasing researches among 
the Clovs mountains, made many, little expected, additions to 
the British Flora. Doubts were stated as to these being realty 
iodigeDoiia, and explanations, the reverse of charitable, were 
oHered of th^r appearance in places which Mr Don was wont 
tovifflt. That a plant stated to be noticed by Mr Don had not 
been re-discovered after his death, was not a reasonable ground 
for doubting his guod faith ; but it cannot be denied, that co- 
lour was ^ven to these su^dons by the re-discovery of ^on- 
chua a^mu in one station only, without a seedling appearing, 
though the station was such as seemed to insure the dispernon

864 Botanicai Muxursums into the Sighianda. 

MhmMrmumimloiiln, 1, 2 — IdATtbet near Foifitf. 

Apa^ia Taramui, I. 9 — ^Frequent on the Ublejuid In th« upper dUtrict of 
CloTB. I cBUDot Me aaj good apedfic diitinction between tliis and A. 
autmBBoRt, »nd I thinli both pass into the A. alpina, which I found in 
1625 and 1827 on the mountains in tiutherlandshire, and in the present 
Btation last year. 

AtM» ptlr^a, I — Near the sununit of Ben-na-muicdui, and at its base, where 
It had bean brought bj the streams, and where oe obserred it to hare 
established itself hi 1 S30. 

Arbulia alpina, 1 Found bjMrWatsoD on Ben Shith (so written, for some 

good reason, I dare say, but pronounced Ben Hee), Ben Lojal, Ben 
Hope, and the moors about Loch Erribidl, in Sutherland t Ben Neris, 
and Cairn Gaiidh, Inyemess-shire; and the hills to the north of Loch 
£11, In Argyleshize. 

^sfnvo'tu alpinut, 1, 2 — This was onlj fotmd in the station where it was first 
recognised, and seen abundantl; last year. The station of Orj/tropit 
eampeilrii was most careHiUy examined for it by both parties, but not s 
tot of it was finind. He Watson U now therefin^ dispwed to think that 
his belief tliat he law it there last year originated in a mistake, and con- 
sequently we only know one station for the epedes. 
' Corax agualilit, WahL 2. — Very abundant in bogs on the extended table-land 
in the upper district of CloTa. This Carex ha»been many years known 
In this station, and particularly was first remaiked as peculiar in Its ap- 
peuancs by Mr Walion in our excurriiw last year ; but though its cha- 
racters did not well agree either with C. tumta or C. ttrieta, it was hesi- 
tatingly referred to one or other of these. On our return to Edinbui^ 
this season, Dr Greville found in his herbarium a spednien from Fries, 
under the name here adopted. It is undoubtedly identical with the 
Clora plant, and agrees in all material p<iint8 so well with the cbai&cter 
in Flora Lappouica, tiiat I do not hesitate to agree with Dr Grerille 
that thus another Carer may be added to the British Flora, It scarcely 
ever exceeds a foot and a half in height, and is often much less; where- 
as Wahlenberg desmbes his plant as sometimes nearly equalling the 
hed^t of a man. In lower ground, and in sheltered situations, I enter- 
. taiBDodoubl that out plant would acquire a much larger size. We ne- 
ver obKrred it bdow Ae taUoJand, though it reached the edges of this 
in almost every direction, filling thelx^ in many places with its creep. 
Ing roots, and visible at a distance by its large foliaceous bractese, rigid 
slightly curved aspect, and pale green cobur. I aught to add, that the 
plant distdbuted by the Unio Itineraiia, as Carex aquatilit, is altogvtiier 
difierent%im ours, and seems to me nothing but C. os^itDso. 

^_ atrata, 1, 2 — Found in great abundknce on almost every cliff we Tint- 
ed, particularly on the south side of the Fee, and in Glen Ida. 

.^—piilla, I, 3.1 — We saw this onl^ in <Hie station, on wet places amang 
the racks on the south ^e of the Pee. Dr W%ht ftvt gathered it, of 
sudiUBUSualdze{ne9Tty twofiiethlgb), audinallTetpects haring cor- 
responding proportions, that it was with difficulty I eould believe in the 
Identity of the species, though the characters perfectly agreed, till I vi-

sited the ipot, ud found UDoni^ the Ii^er speciineni oUmm giwhiaUj 
earning down newl; to tbe (ize I had found it on other mDuutaiiiB. Mr 
Watson alone of the flnt party (bund thii speciea, not in CloTa, hut 
Karcebr of itt unial sice, on Calm Gaildh, near Ben Neria. 
Canx roft/hra, 1, 2 — The first partj found this hitherto scarce Cartx In one 
new station, we at least In a dozen ; and there is not a doubt that It ex- 
ists tu the utmost proAinon in almost uyerj beg on the table-land. 
I Fahm, 1, 9.— Mr Brand, who accompanied the first putj, had the good 
fbrtune to find thie plant in a new station on the south side of the Olen 
of the Dole, near its lower extremity. We only gathered it in the old 
aUtion at Olen Callsder. 
Cieula nimia, 1— Forftr Loch. 

CaMearia ^kinalu, Tar., 3 — Leavea beautifiiUj variegi^ed with broad white 
edgea, or entirely white. I found only tme patch of this on most rocks 
on the south side of the'Fee. The plant wag remarkably vigorous, and 
the leaves v*ry large. 
Mityat oftopetala, 1, i. — On the cliff with Aiiragahu alpimu, in Glen Isla, In 
the parish of Farr, and most abundantly in tbe parish of Dumesi, where 
it is confined to limestone rock. 
EpUabhmt mtguMfi^ium, var. imgu*Htrim»ini, 2.— Dr Orerille found this in the 
descent to Olen Ida. It had a very peculiar appearance, was not in 
flower, but seemed distingulaliable only by the eztrone narrowness of 
its leaves, varying Arum 3 to 4} lines. 
Bqmtehm Drvmmondii, I, — In a ditch by the road ride, about fbur niila» porth 

of For&r, and on the banks of the Caledonian Canai, near its east and. 
Erigfron alpimu, ), 2.— Both in Clova and Glen lela, but especially in the 

latter, where Dr Wight gathered a few specimens with two flowers. 
GoKion patillum, 2.— I gathered Uiis sparingly near the OxglnpU eamptttrit. 
GenMona mvaXi, 3.— Found in abundance at a moderate lieigfat npon the 
nx^B on both sides of Olen Isla by Dr Greville, Dr Wight and myself 
varying from a simple stem, scarcely a quarter of an inch high, to one 
greatly branched, and 6 inches in height, but always with tktweca of 
equal beauty, and not differing proportionally in size. Tbe sparkling 
of this most rare and lovely little gem among the scanty mountain her- 
bage, cured me of hunger and thirst, and made me (bi^ tiiat I was 
gathering it at tbe risk of my neck, for wbicb I have in genenU on such 
occasions a regard at least equal to its value. 
GMcli/eTtt rtpent, l_^bundantly in old fir woods at Cawdor Castle and at 

Oordon Castle. 
iMiM^a borealU, I, 2.— Mr Watson first feund this in vast profUMon, and co- 
vered with flowers, among the heatb at a consideraUe distance from any 
trees, on the south ^e of the Olen of tbe Dole, and a Uttl* way from 
the stream. 
Lgdmu aipbia, 2, — This very interesting plant, not bdore fbund in Britain, 
except by Hi Don, was gathered by Sir John Ogilvy on the aotb of 
July- We went to the station next day, and gathered it in abvndance, 
and in fbll-fiower. Tbe locality is circumscribed, but Mr UiOMb af- 
terwanlB observed it in smaller quantity on another spot, at a little dis-

tance on the wme mountain. It ffoma on ■ bare, Atj, tMay nimniit, 
or in the edge* (rf' the immediitelv adjeintBg peat, at an eleratioa wtiidi, 
ytigaifi from the heights aacntoineil by Mr Wation, I lUppoae maj be 
about 3390 feet above the lea. The rock in both itationa ii a mixture 
of felijiar and t»lc, ii much weathered, hai a deep Kream colour, and is 
quite different from anj thing around. We obierved that lu thti same 
■pota groir ^niKn« rndgmnt^ CaMearim ^fianoHt, and Cbarbri^ tioida, 
and there only at this elevation. A ^epherd whom we met uptm Use 
ground hdd us he had seen the plant ((rowing on a mountain top, either 
between the Glen of the Dole and Bachnagaintjor between thb' and 
Lochnagar, I am-uncertain which, because, aa he evidently did not dia. 
tinguish between the Amelia and Lgdum, I paid little attentim to his 
report at the mom«9t| bat reflecting since on the one never haviog 
been seen without the other on theae mountain topi, I think the ibep* 
herd's accuracy should have been inquired into. The capsule of LytA- 
nli ai^inu is defined as unilocular. Our plant, which i»certainly that of 
UnuKUK, u I learn from Mr U. Don, wbo has compared it with the 
Linneanherberium, ismoat distinctly S-locular when &r advanced to 
ripeness. Whether the dissepiments ultimately dis^pear, whether the 
Hwisa plant is In this reapect difierent &om ours, or whether Uie des- 

1 oription of iJ( capsule be incorrect, I am ucable, from want of ripe fruit, 
to determine. 

Malaxi* fwIudMo, 1, 2. — This we found in many ntuatlons, and in lai^ 
quantity. In the bogt and by the aidea of the rills in the vallej of Clova, 
or a few feet up the meuntdna on both ndea. 

IteSaia dspauparatu, 2. — Extremely vigorous, and in large quantity, on the 
cUfT near the Oiflropii can^mtm. 

NattarHiaK Itmttrt, 1, 2 — Not a common plant in Scotland, but found by 
the^first party near the Lech of Fot&r, and by Dt Wight near JUcb> 

Nvp^r piKtila, 1 — In vaiious statious. 

Paa alpma, 2. — In lari^e quantity In Glen Isla, and not in a viv^Ntrous state. 

PatentUia alpMlru, 2.— Widely distributed on the rocks to the south of the 
Fee, sod in Glen Isla. 

Priimila leatica, l_Fnund by Mr Watson in vaiious stations from Thurso 
toFarr. Soaw of the specimens have several long single-flowered scapes, 
the same variety of fbim which separates Prwiuta vuigatit from P. elatior. 

Pfrvia nttrnd^aUa, 1, 3.— Very sparingly in Glen Dole. 

MDundo, 1, 2.— Much mure common than the last on rock* in vaiious 

places in Clova. 

SaRa lanaUif 1, S. — Both male and fenude plant* in graat perfection on many 
rocks in Glen Dole, Glen [sb, and Glen Caliader. 

T9miarinifi>liaf I. — Probably from the same buab as that seen by Dr 

GreviUe tw% years ago, and in no better condition. 

SaMJn^ uupiloM, 1 — Picked by Mr Barry, but sparingly, in the suae •!■ 
tuation as that in which it was seen by him last year. 

niealii, 1, 9.— Jn tolerable quantity in Clova, but much mora abundant- 
ly, and ia better onditton, in Glen Isla.

Silan ooaufu, tu'. flor. bO. I.— In coniidenble qiuntitj on the Bummit of 
Ben-na-mnic-dul, and on the south side of Glen Dole. 

SoncAiu o/jrinui, 1, i. — Found in five new stations in Glen Dole and Glen 
Ida hj Dr Wight, Dr Greene of Borton, U. 8., and Dr Grerilie. The 
first partj found it <nilj In the old station, where, from being conabmtly 
plundered,, it U becoming weaker every jear. Fortunately some of the 
new statloiu are wholly inacceidble. 

Jtrofiote sMdst, 1. — In the Loch of Forfar, where it was introduced by Mr 

T9ii(upi alpetlrt, 2.— New to ScoUuid. I gtihered a few spedmens at the 
foot of the rocka in Glen Isla. 

Ptraaiom-a^iaa, 1, 2 — Kiceedingly common all over the banks of the White 
Water, in Glen Dole, upon the Fee, in Glen laU, Glen Calkder, and 
the Aberdeenshire mountains near Castletown. It is not common in 
the other parts of Scotland which I have vidted. Mr Watson found a 
few spedmena on Calm Garidli. 

ta^tUUit, I, 2 — Common In Glen Dole ; but in much larger quantity, 

and of much greater size, in Glen Isla. 

IVooMa Itt/perborea, 2 A ringle tutl was found by Dr Greville in Glen lata.

Observatuint of Mr Hewbtt WAvaas*. . 
Absolute altitude is of bo little importance ia the geography 
«f f^Dta, that my attentioQ was for the most part limited to 
the observaUon of their relative heights in regard to each other. 
For this purpose, however, it was necessary to determine the 
hoghts of a few species most commonly met with, as points of 
comparison and reference. The fallowing are the averages of 
various observations^ made near the places mentioned ; the nu- 
merals denoling the altitudes above the sea-level in feet f . 

' We trust Mr Watson will continue hia interesting inTestigatioQa, and 
in' bis next communication inform us how hii heights of stations were ascer^ 
tained. — Edit.

Taking Braemar as the standard, it is found, from the ave- 
rage of the first table, that a similar climate in Clova is 125 
feet above this ; while at Fort William it is 269, and at Tongue 
595 feet below it. The difference ia greater at lower elevations, 
80 that v^etation, both natural and cultivated, is very litde 
better near the sea-level at Tongue than we find it at a thousand 
feet above thia on the hanks of the Dee. The influence of si- 
tuation is well exemplified by the fact that Empetrum nigrum, 
under the steep snow rocks on the northern side of Ben Nevis, 
ftiils 600 feel below its height on the western side ; and Cai- 
htna vulgaris, on the northern precipitous slope of Coini Ga- 
ridh, ceases 400 feet below its limit on the western declivity of 
the same mountain- In our ascent, we find the following plants 
about 1500 feet below Carex rtgida : 

Saxifraga fdzoidea. Tofieldia palustris. 

Alcbenilla alpina. Epilobium aldniliitium.

find the upper limits of the oak, ash, beech, sycamore, holly, 
cherry, and hawthorn. The roses and shrubby brambles (ex- 
cept Rubua idceua) are almost equally distant; sad with them 
is found the upper limit of agriculture. At Clova, UUx euro- 
pcBUS exceeds cultivation by six or seven hundred feet; in the 
other three stations it is rather below. In ncne of them does 
the climate admit the successful cultivation of wheat : Braemar 
is too high ; Fort William is too wet ; Glen Clova, a narrow 
valley shaded from the sun by high hilts; and Tongut, exposed 
to a north sea, and with high ground to the south : — all there- 
fore are equally unsuited. At Clova it has been tried, but 
failed to ripen.

promises to be a very handsome additloa to the species in cultivation, 
aud is now flowering must freely in tbe greenhouse of the Botanic Gar- 
den, £dinbuifll, to which establishment it was obligingly communicated 
from the CSapton nursery. The first amentum expanded its llowen in 
the b^inning of September, but as the whole plant is covered with 
others in all stages they will probably expand in succession fbr a veijr 
long while.

Seeds of this plant were sent along with specimens to this country (rom St 
ZA)uis, North America, by Mr Drummond. The plants powered in the 
greenhouse of the Botanic Garden in August and September. The only 
difference between the cultivated and wild spedmens arises from the 
greater vigour of the former : they are larger, and the leaves are nearly 
rhomboid.

Owiea very numerous, and closely imbricated. 
The seeds of this very fine species were received from my friend Mr 
Cructsbanki, and were probably gathered somewhere in the neighbour- 
hood of Lima, but at a considerable elevation, for the plant is quite 
bardy, and has flowered in the 0]>en air at the Royal Botanic Gu^en 
during the kst two seasons. It is very deserving of cultivatiOB. It 
most nearly resembles O, laraxacifolia, but is distinguished from this by 
Us less prostrate growth ; by the green colour of ita stem ; by tbe cap- 
sule being more attenuated at its base ; by the absence of the conspi- 
cuous glands and hairs, which are miied in O. taramcifiilia with the finer 
pubescence on the ca]:sule and stem; and by the tinge of yellow, not of 
purple, in the flower. Its foliage more nearly resembles that of O. tri- 
loba, but it is distinguished from this by its much greater size, by its 
nearly white flowers, and by its much darker foliage. From both, tnese 
■pedes it is &rtlier distinguished, by the flowers bdng altogether dif.

3. The Netn Vaetmm Sitgar.—The grains of this beantiAil 
Bi^r are true and well-formed crystals. They do not melt so 
readily ite common sugar,— a circumstance that induces some 
inaccurate observers to imaging -that this sugar is not so sweet 
as eominon mu9covada. Thetasteisjusttbatof finecStu^. TIm 
Bdvanlage is, that this sugar is far less hygroraetncfhan common 
law sugar, and suffers less from a mMst atmoephere. The ap- 
paratus used in its pi«pardtion is a modification of the lafe Mr 
Hdvard's apparatus fbr belling sugar in vacuo; 4ith dtraitieM 
of eopper-plates pierced with minute boles, or several fold* t^ 
n^e^^auze for clarlfying^ the syrup. T4)e process iSj imme- 
diately on crusbing the canes, to heat, lime, and scum the 
jutoe; *bich, while ■wanto, is fdeced throilgh the str^ner, froirt 
■n*i6h ' if runs into the boilers. These are provided with air- 
tight covers, the tops of «4)iefa ^re connectedly tubes witfaa 
large ait^ump, wrought by a steam engine. The ateanl, as 
generated, is thus drawn off, and the boiling is carried on at a 
temperature far below the boiling point of sugar. Wfeen suf- 
ficiently concentratedi the syrup is crj^staltiBeJj and, when con- 
solidated, It ifi carried to the cunng-bouse, the temperature of 
which is kept up by steam-prpes mmiing into it. This profieM 
saves much sugar, fbr the heating being low, little or no molasses 
are fbrmed, and a large quantity of sugar is obtained, whibb^ in 
the old procecn, is converted into molasses. VChw af^rattn 
was adopted by sugar-growers in Demerara, on the auggiMtion ■ 
of a distinguished philosopher in Liverpool. The experiment 
has succeeded admirably; and the sugar bears A premium ta 
the Liva-pool market, especially when required ftr ooflfte. ' •

8. On Ae Grease <^ fllne«.—- White wine is subject to an 
atteratioa whkh is deagnated in Switzwlaad, and other coun- 
tries, by the terms greaty and rojpy, {toumra- au gras, grainer, 
filer), a change which takes place after the vioous fermentation 
has apparently ceased, anA the wine has been bottled or closely 
eonfined in casks. The wines of Chunpagne, <^ Switzerhnd, 
and most thin and light winea, are very sutgect to it, especially 
when the vintage has been wet. The cause <4 this mdady r«< 
sides in a mucilaginous principle which is devek^ied in light 
wines : it 'pervades the whole mass, and puts on a reticulated 
appearance; a similar change is observable in beer, and in 
syrups made of sugar of an inferior quality. Various methods 
have been pursued for remedying this defect. Commcm salt 
is added to the wine, a ]wactice which was adopted, it is 
said, by the Romans, in consequence of an accidental disoo- 
very of an amateur in wines. Having opened an am^^ora 
of wine, and being struck with its excellence, he demanded 
of his slave what he had put in it. The latter, mistaking 
his master's meaning, fell on his knees and confessed he hod 
drank a little wine and filled up the vessel with seo-watH*. 
After two or three months, it is impossiUe for the moat ddicate 
palate to distinguisb the taste of salt, and it is admitted that 
such an addition improves the taste of the wine, but that it pre- 
vents the grease is a point much more doubtful. AQoth«' re- 
medy is Um addition of brandy or alcohol. But the more dB< 
carious means of all is a frequent racking off, or decantation. 
Wine must never be alk>wed to icAt^en, that is, to admit the 
rinng of a milky subsioQce, which destroys its tran^Mrency. 
Wh»i this disease has been contracted, it may oRen be removed 
by clarification with fish glue ; but this remedy has two incon^ 
veniencesyit does not always succeed, and when it does, it di- 
minishes the strength of the wine. This deterioration arises either 
fr(Hn the glue, or perhaps from the disease itself, which has occa- 
sioned the operation. Another method of clarifying wines and re- 
moving the grease, consists in filtering them through shavings uf 
hazel. For small quantities this method is very good. When the 
sale of wine is not pressing, and care is taken to keep the vases 
which contain them full, and they arc allowed to undergo a slow 
and insensible fermentaiion, and are exposed to the change of 
temperature which the season brings round, this disease spon-

animal ia abut up in a cage, but.Uttle larger ijun iu body, and

quprt of: cmde peas. The/ am introduced with a fingec into 
the pharynx of the animal, which is thus made to swallow this 
enonnous quantity of nounsbmept, and is then immedwtely 
shut up io its cage. The immediate result (^ tliis kind of life 
is a remarkaUe obesity, and an enormous development of the 
liseTr which, without any notable change of structure, attuned 
~ia triple, or quadruple enlargement of vohime. Bibulous pflptr

Borba an oily m^ter, much like melted fat. These Uver» aome- 
times weigh ei^t or ten otnces^ and sell at frmn three to fire

lion, for every part of tbe animal pusseEses an intriiiBic value ; 
the tat on many occasions is a substitiue for butler, and tbe 
fleda is served at table, and althou^ somewhat tough, is not

some time nnce disMvexed tbe process of making starch' into 
sugar, has lately made several experiments upon milk: the result 
of wbicb he h^ arrived at is curious. He is satd to have found 
a nude of keeping milk for use for any definite . space cf time. 
The process of preserving is this : he causes aew milk to be 
evaporated over a slow fire, until it is reduced to a powder. 
This powder is then put into a bottle, which is hermetically 
sealed. Whfn the milk is wanttd for use, it is only to dissolve 
some of the powder in a seasonable quantity of water, and the 
naixtuce so dissolved -will have all the qualities, as well as the 
taste, nf milk. — ES/nburgh JgriatUuralJoumai.

of veryconsiderable impu'tanGe in a couimennal pcunt of view. 
Vast qnantiiiffl are brou^t from the couotry to LondoD, and 
other great towns. Since the peace they have also been 
largely imported from t}ie continent. At tbb moment, indeed, 
the trade in eggs forms a considerable branch of our commerce 
frith France, and affords constant employment for a anmber of 
small vessels. ' It appears from official statements, that the eggs 
impelled from France amount to about 60,000,000 a-year ; and 
supposing them to cost, at an average, 4d. per dozen, it foUowft 
that the people of the metropolis and Drighton (for it ie into 
them that almost all are imported), pay the French above 
t,. 88,000 a-year for eggs ; and supposing- that the freight, im- 
porter's and retafler*s profit, duty, &c. raise their' price to die 
consumer to lOd. per dozen, their total cost will be L.S1S,000. 
The duty in 1829 amounted to 'L.m,\%%—MacCi^ocK3 Cotr^

eggs exported from Bernack-upon-Tweed to London amounted 
to L. 80,000 worth a-year.]— £di«AurgA AgricuUvral Joumt^ 
7. Destruction of Fresh-water Figh by the admitaion cf the 
Sea into a Lake. — The following particulars of the phenomena 
attending the opening of Lake Lothing at Lowestoft to the Sesy 
where sea-borne vessels were first received into the new harbour 
at that place on the Sd of June last, may prove of inter^t in 
natural history. They are extracted from the East Anglian 
Newspaper of June 7. 1831. Some of the circumstances at- 
tending the junction of the salt and fresh waters in the first in- 
staoc£ are remarkable. The salt-water entered the lake with a 
strong under current, the fresh-water running out at the same 
time to the sea upon the surface. The fresh-water <rf the lake 
was raised to the top by the eruption of the salt-water beneath^ 
and an immense quantity of yeast^like scum rose to the surface 
of the lake. The entire body of the water in the lake wbs ele- 
vated above its former level ; and, on putting a pole ddirn, 8 
strong under-current could be felt bearing it from the seii; and 
at a short distance from the loch, next the lalte, there was a per^ 
ceptible and clearly defined line where the sah- water and the 
fresh met, the former rlishing under the latter, and upon this 
line salt-water might have been taken up in one hand and fresh 
in the other. The consequences of the admission of the briny 
waters have been fatal to thousands of the former inhabitants of

bodies of pke, carp, perch, bream, roach, and dace, multitudes 
of which were carried into the ocean, and thrown afWwards 
upon the beach, most of them having been bitten in two by the 
dog-6Bh, which abound in the bay. It .is a singulur foct that a 
{nke of about 20 lb. w^ght was taken up dead near the Mut- 
ford end of the lake, and, on opening the stomach, a herring

9. tfn Subterraiuous and Ominoui Sound*j—Ja a tanoer 
▼oluincof the Journal, we communicAted some cutious details 
in regard to what have been called subterranean andommtmg 
sounds. Sir John Hersuhell has lately considered this subject, 
and conjectures that the nuises of Nakoos, hi Atabis, tnay be 
owing to a aubterraneous production of steam, by the generation 
and condensation of which, under certain circumstances, sounds 
are well known to be produced. They belong to the same class 
of phenomena as the combustion of a jet of hydrogen gas in 
glass tubes. He also remarks, that wherever extensive subter- 
raneous caverns exist, communicating with each other, or with 
the atmosphere, by means of small orifices, considerable diffis 
Fences of temperature may occasion currents of Mr to pass 
through those apertures with suHicient Telocity for producing 
sonorous vibrations. The sounds described by Humboldt, as 
heard at sunrise, by those who sleep on certain granitic rock^ 
on the banks of the Orinoco, may be explained on this principle. 
The sounds produced at sunrise, by the statne of Memnon, and 
the twang, like the breaking of a string, heard by the French 
naturalists to proceed from a gmnite mountain at CanraC, an: 
viewed by him as referable to a different cause, viz. to pyrome- 
tric expansions and contractions of the heterogeneous material 
of which the statue and mountain consist. Similar sounds, and 
from the same cause, are emitted when heat is applied to any 
connected mass of machinery ; and the snapping often heard in 
the bars of a grate aiTords a familiar example of this phettomencn. 
The following amusing account of an ominous sound is^venby 
Gairdner in his book on the " Music of Nature :"— In one of 
the baronial castles of the north, vbtch htta been'tinirihalnted for 
years, there were heard at times' such extraordinary jwiisea, as to 
confirm the opinion among the country people that the place 
was haunted. In the western tower an old couple were per- 
mitted to live, who had been in theSCTviceof tbefonoetterd.but 
so imbued were they with the silperstitions of the cbuhlryj that 
they never went to bed without expecting ' to hear the cries of 
the disturbed spirits of the mansion. An old story was current, 
that an heir-apparent had been tnurdefed by an 4fnol«T' that he 
might possess the esiate, who, however, after enjoying •it for a 
tjnae, was so annoyed by the sounds in the castle, that he re- 
tired with an uneasy conscience from the domain, and died 'in 



Scieiityic iMieUiffemx.-^Gmioglf. 076 

FrflUOe. Not many jedrs ago, the [iroperty descended tb > 
bmach of the female lide (one of the heron of Waterloo), wlio, 
BothiDg daunted, was determined to make this castle his place 
ef rMidettca. As the noisefi were a subject of real t«'rar to his 
teMDIry, he formed the reaalutitni of eleefnng in the castle oa 
tiM flight he took poBaemon, iii order to do away these super- 
Mllious fears. Not a habitable nxnn could be found, except 
the otle OGOUpied by the old gardener and-his wife in the western 
turret, and he ordered hb camp-bed to be set up in that apart- 
Meflt. It was in the autumn, at nightfall, that he repaired to 
the gloomy abode, leaving his servant, to his no small comfort, 
at tlie village inn ; and after having found every thing com- 
fortably provided, turned the large old rusty key upon the an- 
tiquated pair, who took leave of him to lodge at a farm hard 
by. It was one of those nights which are checkered with occa- 
sional gleams of nwonshine and darkness, when the clouds are 
riding in a high wind. He slept wdl for the two first hours ; 
be was then wakened by a low mournful sound that ran through 
the apartments. This warned him to be up and accoutred. 
He descended the turret stmrs with a bnlliant li^t, which, on 
tioming to the ground floor, cast a gigantic shadow of himself 
upon the high embattled w^ls. Here he stood and listened, 
-when presently a hollow moan ran through the long corridor, 
and died away. This was followed by one of a higher key, a 
sort of scream, which directed his footstepg with more certainty 
to the spot. Pursuit^ the sounds, he found himself in the hall 
of his ancestors, and vaulting upon she large oaken table, set 
down his lamp, and folding his cloak about him, determined to 
wait for the appearance of all that waa terrible. The night, 
whtcb had been stormy, became auddeiily still ; the dark flitting 
clouds bad Mink below the horizon, and the moon insinuat<<d 
her sUvery light through the chinks of the mouldering pile. 
As oui* hero had spent the morning in the chaBe, Morpheus 
cAtne unlndden, and he fell asleep upon the table. His dream 
was short ; for close upon him iastied forth the horrid groan ) 
amazed, he started up and sprang at the unseen voice, fixings 
with a powerful blow, his Toledo steel in the atrds. The blade 
WUi fast, and lield him to the spot. At this iHometn the moon 
shot a ray that illumined the hall, and showed that beldnd the 
waving ftJds there lay the CBUse concealed. His sword he left,

11. On the Permanettce qf the Earth's Axis <^ Rotation. — 
" It appears," says Mrs Somerville, in her admirable .work) 
" from the marine shells found on the tops of the highest 
nujuntaiDH, and in almost every part of the globe, that imm^i^ 
continents have been elevated above the ocean, which.(ocean) 
must have engulfed others. Such a catasti;ophc would t^of- 
casioned by a. variation in the pout ion of the axis pf /otad^^on 
the surface of the earth ; for the seas tending to (he-new etjuatw 
would leave some portions of the. globe and overwhelirt others. 
But theory proves that neither rotation, preces^on, nor any of 
the disturbing forces which afiect the system, have the smallest 
influence on the axis of rotation, which miintains a p^r^anoit 
portion on the surface, if the earth be not disturbed in its rotar 
tion by some foreign cause, as the collision of a comet, which 
mi^ have happened in the .immeBsity 4^ time. Then*. indeed, 
the equilibrium could only h«ve been restored by tbis. rushtsg .of 
the seas to the new equator, which they would continue to do 
till their surface was every where perpendicular to the direftisn

of gravity. But H is probable that nidi as acCumillMion of the- 
waters wonld dm be nifiaent to resttMc equitfinium, if the de- 
rangement had been great; fix- the meaa deority of the sea is. 
only about a fifth part of that of tbeeartli-; and the mean depth, 
evea ct the Padfie Ocean, is not more thoD four iiB^e% whereaft 
the equatorial radius of the earth exceeds the ftiaT radius by 
twenty-fire or thirty miles ; consequently, the influesce at the 
sen on the directioB c^ gravity, is veiy snwU : aad, as it' (bu» 
iqipearB that a great cfaasge ob the pontna of the axis is ineoiM- 
{latiUe vitb the Uwof equilibnwn, the geolt^cal phabomeitii 
mttstbe afcribed to an tntonal oauw. Thas,aa)tdst ibeki^lHy 
levolutions whkh have swept inmimeraUe mces «t orgBMwd 
beings ftom the earth, which have elevatiid i^Bins, and buried 
mountains in the ocean,— the rotation of the earth, and the po- 
sition of die axis«n its surface, have undergone but slight va- 
riations."

IS. Iti^an Ct^ee. — In a communication from India to I^ 
Traill, it is stat«^ that a Dr Strong has succeedbd in raising a 
marketable coffee, in some quandty, at Russypugla, about five 
miles from Calcutta. The attempt futed in the hands of Sr 
Wallich, and those of Messrs Palmer and Company, who tried 
it on a large scale. The secret of Dr Strong''s success is in cul- 
tivating his plants in the sun, not in the «hade. He states, 
when cultivated in the shade of other trees, as has been recom. 
mended by some, the roots and brandies are more scanty thaii 
when they grow in the /uS «m. We expect, in our next 
Number, to report as to the qualities of the cc^ee, from expe- 
riments made in this country. Dr Strong says that if they can 
succeed in the formation of artesian wells, the Cultivation may 
be extensively carried on in his neighbourhood, and with great 
prospect of iu becoming a grand article of commerce. Should 
it equal, or be near in quality, to Mocha coffee, it will undoubt- 
edly be of vast impcirtance to Bengal. 



13. Academt/ <fSt Prtfr#&«r^.— The sixth aeriet of the Me- 
mwrs of this Academy comn>ences at the centenary celebration 
of this learned body, held in 18S6. Up to this date, the com- 
plete collection of its volumes comprehends five series, each of

which ia mariced by a chKnge of title. From ttte fuundation of 
the Academy id 1786, to 1SS8, the Latin language wat the 
medium of commuiucatioa. The fint srriea, calird Commenta* 
rits {Caimmentarii)^ axtended from 1736 to 1747 1 tb&t ie, from 
the inaugumtion oT the Bcadeiny, by the Eiupren Catherine I.^ 
until the fimpreu £listd)eth afleoted some new regulation^ 
Tbia aeries is in foarieen Tolunwa. From 174>7 to 1776, thent 
«re twBnty-one voluunea of Naoi Commenlar^. The celebration 
of the semi'Hecukr jatrilee eetablithed a new ^XKhj from which 
the iHiblteationi are called Atta. Twelve volumes of these 
bring the labours of the Aoadtmy to the year 1788, a memora- 
ble year, in which the academy was placed under the directiroi 
ei Ute FriaceM DaschkofF, for in Ruiaia there it no Salic law, 
even in the government of letters and sdenee. Under the new 
Direoteur (such was the title given to this lady by the Imperial 
ukase, nhich invested her with the direction of the Academy)) 
6(Wn volumes of Nmta Acta terminate the publication in Latin . 
The year 1808 was an important period to the Academy ; the 
Em\)eroi AJenander gave it new laws, and the French language 
woa lubatituted for the La4*B. But the peiiod was unfavour< 
aUe to acadenuc labours ; so that, from 18031D MflSj-biU^leVfu 
volumes a{^)eBred, forming the ^/ih uries, under the title Me- 
tttMres. Lastly, a niode of publication more useful than that of 
entire volumes, viz. thftt of parts or livraisons, baa been adopted.
